Hearing Loss

Most of us associate hearing loss with old age, but it is increasingly common for children and teens to suffer from mild to moderate hearing loss. Nearly 15% of kids have hearing loss according to the CDC. Hearing loss can be due to many things that are difficult to control, such as heredity, infection, and medications. In kids and teens it is oven due to a preventable cause: noise.

Where does the excessive noise come from?

Even young children are exposed to more loud noises through toys, television, and gaming devices than children of years past.

Widespread use of ear buds for prolonged periods can take its toll on hearing. Unlike the bulky headphones used when I was a child, earbuds deliver sound directly into the ear canal without any sound buffering in between. Most often the earbuds are used with iPods and other mp3 players are low to mediocre quality, so they are unable to transit the bass as effectively. Many kids turn the music up to hear the bass. If others can hear the music coming from ear buds, they are too loud!

Loud concerts or sporting events can also expose our ears to excessive volumes for a prolonged period of time.

Not all excessive noise is from kids being undisciplined - some kids are helping out the family or trying to earn extra cash by mowing lawns or using power tools, which puts them at increased risk.

How much is too much?

According to the Centers for Disease Control and Prevention (CDC), being exposed to more than 85 decibels (dB) of sound for eight hours can damage your hearing. At 105 dB, hearing loss is possible after a mere 5 minutes.

If you're like me, that means nothing because how much is 85 dB? There is a great chart of common sounds and how loud they are on this page from the CDC. There are also several free apps available for download on smartphones and tablets - search "sound meter" or "decibel" and read reviews before downloading. Take advantage of these -- and because it's in the phone, kids might actually have fun playing around with them and learning about their environmental risks at the same time!

Signs of hearing loss

One early sign of excessive noise is ringing in the ears, but most people with hearing loss never realize it's happening because it's slowly progressive. If you notice your child asking "what" more often or complaining that the television is too quiet when others hear it well, it is a good idea to have their hearing tested.

Consequences of hearing loss 

There are many potential consequences to hearing loss:

  • Learning - you have to be able to hear the lecture. 
  • Behaviors - if directions and instructions are missed, a child might incorrectly be seen as misbehaving. 
  • Friendships and social skills - if a child can't follow a conversation they aren't easy to talk to or play with.
  • Job availability - many jobs require hearing at a certain level. 


Talk to your kids about the risks of their habits that involve loud sounds. Unfortunately kids won't always take parental advice to heart because they have a feeling of invincibility, but studies show if they learn about hearing loss they are more likely to use protection. Even more so, what their friends are doing alters their behavior. Teach not only your kids, but also their friends. If they're all going to a loud event, consider giving them all ear plugs. Once hearing is damaged they can't gain the hearing back, so prevention is key.

Ways to protect include:
  • Wear hearing protection (earplugs) when mowing the grass and attending loud events, such as concerts or sporting events.
  • Turn down your music! Some music players have alerts when the volume goes too loud, but those can be ignored if the child doesn't understand why it's important to lower the volume. If others can hear the music you're listening to through earbuds, turn it down.
  • Lower the maximum volume setting on your iPod or mp3 player. To do this, go to "Settings" and select "Volume Limit" under Music. Set it at about 60% of the full volume, that way you can't accidentally turn your music too high.
  • Use big headphones instead of earbuds. They offer more external noise cancelling, which allows the music to be heard better at lower volumes. They are also physically further from your eardrum, which helps.
  • If you must use earbuds, use high quality buds that transmit bass if you are tempted to turn music up to hear the bass.
  • Follow the 60/60 rule: No more than 60 minutes of listening at a time, and no higher than 60 percent of maximum volume. If you go under "settings," you can actually set your iPod for maximum volume setting of 60 percent, so you can't accidentally turn your music up too loud.
  • Higher pitched sounds have greater potential to damage your ears than lower pitched sounds. Turn down the volume when a high-pitched song comes on.
  • Try not to fall asleep with earbuds or headphones on. The time of exposure matters and why waste sleep time damaging your ears? 
  • If you need "white noise" to fall to sleep, put together a playlist of soft songs or sounds and have it play at a low volume from a speaker on your bedside table. Use your clock's "sleep" function, which will automatically turn off your music after a set amount of time to ensure the music doesn't end up playing all night long, which saves energy in addition to your hearing.
  • As always: model these behaviors for your children. If they see you mowing the grass with loud music blaring in your ears, they will grow up to do the same. If you wear ear buds many hours of the day, they will see that as a normal and acceptable behavior. 

What happens that hurts our hearing?

Keep the volume down – Too loud and too long can damage your hearing shows a man listening to music. Below it the music soundtrack and volume levels are shown. The video then breaks to showing what happens to the hair cells in our ear with these volumes, which makes the damage more understandable because you can see it happening.

Flat heads in babies

We have significantly decreased the risk of SIDS by placing babies on their backs to sleep, but have seen a rise in flat heads due to their positioning. Prevention of the flatness involves several positioning strategies.
Supervise tummy time when Baby's awake!

It's important for babies to sleep on their back, but they tend to have their head facing one direction or another. They should alternate which side they face, but many babies have a stiff neck and favor looking to one side. Think of when you wake with a stiff neck - probably from positioning overnight. Many babies are in the same position for quite awhile at the end of pregnancy - of course they're stiff!

If Baby's neck is stiff, you can massage his or her neck and shoulder muscles gently and then slowly move the head right and left (chin to each shoulder) and side to side (ear to shoulder). Don't quickly force the head movement, but think of what you do if you have a stiff and sore neck. The more frequently you stretch it out, the better it feels, right? I recommend stretching Baby's neck with each diaper change (before the change or after you wash your hands!) until it isn't stiff for several days and Baby moves his or her head easily without your help.

Start supervised tummy time early on - the longer you wait to start, the more Baby might resist it. I see so many parents who are hesitant to put Baby on his or her stomach. Concerns range from the umbilical cord stump still being on and bothering the baby (it won't) to spitting up will worsen (test it out, for many babies it's actually better) to "I thought babies should never be on their stomachs" (only when sleeping or not supervised).

Tummy time is an important time for baby to develop muscle strength. It needs to be supervised, but it can be a fun time to interact with Baby. Lay face to face and talk to Baby, encouraging him or her to look up. Grab a brightly colored object and move it around for Baby to watch. Enjoy your play time.

For more information on issues related to stiff necks in babies and how to treat the stiffness, see this Torticollis information.

Rashes in kids... a few case studies for parents

I am not a dermatologist, but I see rashes all the time. Some are easy to identify, others I'm not sure what the cause is. In general physicians are taught to treat the symptoms of a rash. The standard dermatology lecture in a nutshell is: If it's wet, dry it. If it's dry, wet it. If it itches, use steroids. If it's infected, use antibiotics.

I'll go over a few made up case studies -- each one is a conglomeration of kids I've seen.

Case 1

Parents bring Itchy in for a well visit but mention that her skin has rashes on her elbow creases and behind her knees. Sometimes she scratches them to the point where they bleed. They've tried applying a pink fragrant lotion that they got as a baby gift, but she says it burns and didn't help.

Advice for this family would not include which of the following?

  1. Use the lotion more often since the skin is dry
  2. Stop the lotion because fragrant lotions can worsen this condition
  3. This type of dry skin can be related to allergies and asthma, having one makes it more likely to have another
  4. Controlling the itch is important because scratching worsens the rash

The answer is #1. This rash is most likely eczema, a fancy term for dry skin. It often develops in infants but improves as a child gets older. It is more common in kids with allergies and/or asthma. It can worsen with exposure to irritants (such as a fragranced lotion or soap) and allergens (food allergies and seasonal allergies). I've often heard this called "the itch that rashes". Scratching damages the skin, which allows water to escape, which dries the skin more, leading to more itching. This itch/scratch cycle worsens the rash and can lead to secondary infections. This can be a very frustrating condition because it will come and go for years in some kids. It's important to avoid irritants and use proper skin care. For more treatment, visit Dry Skin / Eczema / Atopic Dermatitis.

Case 2

Parents bring their infant in for her well visit and ask about a rash that's been there "for awhile" but doesn't seem to bother Baby. They aren't sure when it started. They can't recall any new soaps, lotions, foods, or other potential triggers. They describe it as red spots and they aren't sure if they're changing over time. Baby is eating well, gaining weight well, sleeping well, and not fussy. On exam, they show me the rash on the abdomen and arm, but I cannot see any red spots. 

What further questions might I ask and what advice might I give?

  1. If this rash would be on your own skin, how would you treat it?
  2. Treatment of the rash should be based on symptoms, and since there are no symptoms, no treatment is needed
  3. Monitor for signs of itching, fussiness, fever, poor feeding, and other concerns
  4. All of the above

The answer is #4 and yes, I see this non-existent rash all the time. It's not just my old eyes that can't see it -- I hear from pediatrician friends about this phantom rash too. I know parents worry more about their children than they worry about themselves, but sometimes they can realize the unfounded concern when I simply ask what they would do if this rash was on their own skin. Most say they wouldn't worry about it. Enough said. 

Case 3

Parents ask about a rash that appears sometimes after their school aged child showers. It doesn't itch or hurt. It is always on the chest and abdomen and sometimes on the legs. It looks like red splotches. They've tried various soaps and shampoos, but changing them doesn't seem to affect the rash. It isn't present on exam because it only happens after showers and lasts less than 30 minutes. They are concerned because it returns so frequently.

My advice to parents includes which the following?

  1. Treatment of a rash should be based on symptoms, and since there are no symptoms, no treatment is needed
  2. Use only cleansing products made for babies since your child is obviously sensitive to something
  3. Turn down the temperature of the water in the shower to see if the rash "resolves"
  4. 1 and 3
The answer is # 4. Again, I've been asked this type of question more than once. It also falls into the category of "What would you do if you had this rash?" Most parents would admit they wouldn't do anything since it didn't cause any problems and was brief. If they really think about it, they probably have had this "rash" after a hot shower. It's just flushed skin. If you enjoy a hot shower, it's okay if your skin flushes a bit.

Case 4

Mom brings Kiddo in because her nails are growing "funny." They have a horizontal crack and the tips are peeling off. They don't seem to hurt or bother Kiddo.

What further information would be important to know?
  1. Was there any trauma to the nails?
  2. Has your child been sick in the past 2 months?
  3. Does kiddo use nail polish or fake nails?
  4. Does your child pick at her nails regularly?
  5. All of the above.
The answer is #5. The answer is usually in the patient history with this one. I've seen a number of kids with peeling nails recently because we had hand, foot, and mouth in the area about a month ago. Not all kids with that infection lose their nails, but it can happen. For more on this, including pictures, see Four Cases of Onychomadesis after Hand-Foot-Mouth Disease. Other causes of peeling nails include trauma and nail picking, nutritional deficiencies, nail products, chemical irritants, certain medications, infections, and chronic diseases. 

Case 5

Mom brings Snotty in because he's had a runny nose all week. On exam, he's found to have what mom thought was dried mucus under his nose, but the underlying skin is red and it's actually more of a crusting, not mucus. 

Treatment of this includes all except:
  1. Using rubbing alcohol to rub off the crust
  2. Antibiotic ointment
  3. Washing the area
  4. Avoid touching the area
  5. Oral antibiotics
The answer is #1. That would hurt! This is a classic case of impetigo. Impetigo is a bacterial skin infection. It often happens when the skin is damaged (in this case from Snotty wiping his nose constantly) and if bacteria from the nose or mouth get into the skin. It can be treated with prescription topical antibiotic ointment in most cases, but some cases require oral (by mouth) antibiotics. Wash the area gently and soak crusts with warm wet cloths to help remove the crust. Complete removal of the crust isn't necessary though - that will happen naturally as the infection resolves. Touching the area can spread the infection, so avoid touching it and wash hands well after touching it!

Cough 'til you puke...

This is the time of year it seems everyone's coughing. I've heard from more than one worried parent that their child coughs to the point of vomiting. In the medical world, we call this post-tussive emesis.

Post = after, tussive = cough, emesis = vomit

Kids tend to have a very active gag reflex, so they sometimes gag themselves and vomit with cough. This can be good, since it gets the mucus out of the back of the throat. You can try to teach older kids to hack and spit it out, cough and spit it out, gargle with salt water, and rinse mucus out of the nose.

Of course it's not fun to vomit after coughing because everything in the stomach comes up and makes a huge mess. Sometimes the vomit comes out of the nose, which can burn from the stomach acid. And vomiting can be very scary to kids.

Are there serious concerns when kids vomit from coughing? 

Yes. In medical school I learned that when kids cough to the point of vomiting we should consider whooping cough, pneumonia and asthma. In reality, I find that many kids with regular cough and colds can gag from cough, but I always consider the more serious options.

What should I do if my child vomits from a cough?

First, keep your cool. If a parent starts to get flustered, it makes the child more worried, which never helps.

Make sure your child's breathing is okay. Obviously he is coughing, but between coughs if the breathing rate is too fast or labored, he should be evaluated ASAP.

Rinse out your child's mouth (and nose if needed- saline drops or rinses work well for this). Vomit is just nasty tasting and can burn in the nose.

Treat the cough. If your child has asthma, give a breathing treatment or their rescue inhaler. If your child is over a year of age, you can use honey to help a cough. A tsp usually does the trick. Humidify the air with a vaporizer or humidifier. For more treatments see Cough Medicine: Which one's best.

When should my child be seen?

If your infant is under a year of age or your child has not had the whooping cough vaccines, he should be evaluated. Some babies with whooping cough stop breathing so many are hospitalized to monitor for complications. 

After a single episode of vomiting if your child's breathing is comfortable, just continue to manage at home.

If your child develops difficulty breathing or dehydration, he should be seen as soon as possible.

If your child continues to vomit after coughing but is comfortable between episodes, he should be seen during normal business hours at his regular doctor's office.

Help! I'm sick and I have a baby at home.

When we have newborns we don't want to expose them to germs. We avoid large crowds, especially during the sick season. We won't let anyone who hasn't washed their hands hold our precious baby. We might even wash our hands until they crack and bleed.

But what happens when Mom or Dad gets sick? What about older siblings? How can we prevent Baby from getting sick if there are germs in the house?

In most circumstances it is not possible for the primary caretaker to be completely isolated from a baby, but there are things you can do to help prevent Baby from getting sick.

  • Wash hands frequently, especially after touching your face, blowing your nose, eating, using common items (phone, money, etc) and toileting. Wash Baby's hands after diaper changes too. Make this a habit even when you're not sick... you never know when you're shedding those first germs!
  • Wipe down surfaces. Viruses that cause the common cold, flu, and vomiting and diarrhea can live on surfaces longer than many expect. Clean the surfaces of commonly touched things such as doorknobs; handles to drawers, cabinets, and the refrigerator; phones; and money frequently when there is illness in the area. 

  • Avoid touching your eyes, nose and mouth - these are the "doors" germs use to get in and out of your body. Pay attention to how often you do this. Most people touch their face many times a day. This contributes to getting sick.
  • Resist kissing Baby on the face, hands, and feet. I know they're cute and you love to give kisses, but putting germs around their eyes, nose, and mouth allows the germs to get in. They put their hands and feet in their mouth, so those need to stay clean too. 
  • Cover your cough. I often recommend that people cover coughs and sneezes with their elbow to avoid getting germs on their hands and reduce the risk of spreading those germs. When you're responsible for a baby, the baby's head is often in your elbow, so I don't recommend this trick for caretakers of babies. Cover the cough or sneeze with your hands and then wash them with soap and water or use a hand sanitizer if soap and water aren't available.
  • Vaccinate. If you're vaccinated against influenza, whooping cough, and other vaccine preventable diseases, you're less likely to bring those germs home. Encourage everyone around your baby to be vaccinated. If you get your recommended Tdap and seasonal flu vaccine while pregnant, Baby benefits from passive immunity. See Passive Immunity 101: Will Breast Milk Protect My Baby From Getting Sick? by Jody Segrave-Daly, RN, MS, IBCLC to better understand passive immunity.
  • Breastfeed or give expressed breast milk if possible. Mothers frequently fear that breastfeeding while sick isn't good for Baby. The opposite is true - it's very helpful to pass on fighter cells against the germs! Again see Jody Segrave-Daly's blog for wonderful explanation of how breast milk protects our babies. 
  • Limit contact as much as possible. If possible, keep Baby in a separate area away from sick family members. Wash hands after leaving the area of sick people. If the primary caretaker is sick and there is no one available to help, wear a mask and wash hands after touching anything that might be contaminated.
  • Insist on a smoke-free home and car. Even if someone is smoking (or vaping) in another room or at another time, Baby can be exposed to the airborne particles that irritate airways and increase mucus production. These toxic particles remain in a room or car long after smoking has stopped. If you must smoke or vape, go outdoors. Change your shirt (or remove a coat) and wash your hands before holding Baby.
It's never easy being sick, and being a parent adds to the level of difficulty because you not only have to care for yourself, but someone else depends on you too. As with everything, you must take care of yourself before you can help others. Drink plenty of water and get rest! Most of the time medicines don't help us get better, since there aren't great medicines for the common cold. Talk to your doctor to see if you might need anything. Don't be falsely reassured that you aren't contagious if you're on an antibiotic for a cough or cold. If you have a virus (which causes most cough and colds) the antibiotic does nothing. You need to be vigilant against sharing the germs!

Flat heads in babies - What's the best treatment?

Babies often get misshapen heads from laying on one side or even from being squished while still inside mom. The misshaped head is referred to as plagiocephaly, scaphocephaly, or brachycephaly -- depending on the overall shape (see lower photo below). These, especially plagiocephaly, are very common. If I knew I'd one day have a blog, I would have taken pictures showing the head shape of my child who had positional plagiocephaly. That baby is now a teen with a normal head shape, so it's too late for photos. 

Below is a picture of a baby with positional plagiocephaly. Note the flat left back of the head. In this picture you can't see the ears, but we look to see if the ear and forehead are pushed forward to help assess the severity of the plagiocephaly.

The Joint Section on Pediatric Neurosurgery of the American Association of Neurological Surgeons and the Congress of Neurological Surgeons have issued new guidelines for diagnosis of as well as treatment options for plagiocephaly with repositioning, physical therapy and helmets.


Most of the time we can make the diagnosis in the office without any special tests or x-rays. If there is a concern that one of the sutures (growth plates between the bones of the skull) is closed, a skull x-ray or an ultrasound of the area in question can assess if the suture is open or closed. If the diagnosis is still in question after those studies, a CT of the head may be needed. The picture below shows how the skull shape changes if one or more of the sutures is closed (represented by a missing line).

The first treatment used to treat plagiocephaly is repositioning. Repositioning helps with all infants with positional plagiocephaly to some extent. Repositioning is just what it sounds like: change the position of your baby so the side down alternates when sleeping or laying. Put fun items to look at on alternating sides when baby is laying on the back when awake. When feeding, hold baby in alternate arms so when they turn to face you they are looking different directions each feed. (This happens naturally when breastfeeding.) Use supervised tummy time several times each day and hold baby upright as much as possible to get baby off the back of his head when not sleeping. The American Academy of Pediatrics has issued a warning against the use of positioning pillows due to risk of suffocation.  

A stiff neck often is associated with positional plagiocephaly because it limits head movement to one side. The stiff neck is called torticollis. Torticollis makes it difficult for baby to turn his head to one side, but gentle stretching can help. I show parents how to hold one shoulder down while gently moving the head to stretch the neck - with each ear to the shoulder and then the chin to each shoulder. It's important to do a gentle but firm stretch, no jerking or forced movements. Massaging the neck muscles first can help. Think of what you do when you have a sore neck and want to stretch it. Working with a Physical Therapist has been shown to be more effective than repositioning alone and as effective as positioning devices (which are not recommended due to safety concerns).

Babies with persistent moderate to severe plagiocephaly after repositioning and physical therapy may benefit from a helmet to mold the head to a round shape. The helmet corrects more rapidly than positioning alone, so is also used if there is significant plagiocephaly in older infants. I reserve this option for the more severe cases that don't respond to repositioning and physical therapy since it is expensive and often not covered by insurance. I do not know if these recommendations will make it easier for insurance to pay for a helmet when indicated.

Great News About the HPV Vaccine!

The HPV vaccine has been a controversial vaccine on social media, but anyone who knows me knows that I agree with the recommendations and wholeheartedly endorse it for the reasons given in my favorite HPV Vaccine article.

Photo Source: Jan Christian via Wikimedia

To add to the confusion and misinformation that circulates regarding the safety of the vaccine (which I don't have room to go into here, but is discussed herehere, here, and visually here), the vaccine itself has changed (covering 9 strains now compared to the initial 4 strains) and the dosing schedule is changing.

Don't presume the change in vaccine schedule is to answer the calls of the anti-HPV vaccine crowd. That isn't needed because their claims have been debunked (see all the articles referenced above).

Dosing schedule ~ Happy News!

HPV vaccines were initially approved to be administered as a 3-dose series: dose #2 given two months after the first and the 3rd dose at least 4 months after the second. Giving doses later is acceptable, but they cannot be given too early.

There is research that supports giving just two doses at least 6 months apartA two dose schedule was approved earlier in Europe and this week was approved by the FDA in the US for children 9 to 14 years of age. The two doses should be given 6-12 months apart, which means for most kids they can get the vaccine at two regularly scheduled well visits (such as the 11 year exam and the 12 year exam) and not have to come in for additional visits.

The data support continuing a 3 dose series in those 15 years and up. This means they can get the 2nd dose 2 months after the 1st dose and then a 3rd dose at least 4 months after the 2nd dose and 6 months after the 1st dose.

The official ACIP Meeting Information is not yet available, but will be posed within 90 days of the October 19-20 meeting. (Note: I originally stated this was an October 11 meeting.)

I know that the two dose series will make many kids happy ~ one less shot for the same protection!

If two doses have already been given at less than 6 months apart or if the teen is 15 years and older, the third dose will still be needed.


I don't want to confuse everyone... the FDA has approved a new schedule, but the Advisory Committee on Immunization Practices (ACIP) will need to give their input before the schedule actually changes. That will be decided at their October 19-20 meeting.

One last addendum:

The ACIP approved the changes! Talk to your doctor about your child's vaccine needs. In short, the new recommendations state:
  • Kids who get the first HPV vaccine before their 15th birthday need two doses 6-12 months apart.
  • Kids who have turned 15 years old before the first dose should use the 3 dose series.
  • Kids who have gotten a 2nd dose less than 6 months after the first (regardless of age) need the 3rd dose.
