Growing Pains at 10 Months?

Dear Dr. Warren: My son is 10 months old, weighs 21 lbs, and is 31 inches long. He has been growing very fast, and seems to be having a lot of growing pains. I have avoided giving him a lot of pain relievers because I don't want him to build a tolerance or allergy to them.

Is there anything else that I can do to help ease the pain?

-MS

Dear MS: The term growing pains refers to a variety of common muscular pains in growing children related to physical activity. Rapid growth is not painful. Infants may complain for a variety of reasons including teething, gas pains, and separation anxiety. If your son seems to be having a great deal of pain, he should be evaluated by his pediatrician to determine the cause. I am not convinced that a 10 month old has growing pains.

Sincerely,
Dr. Warren

Airplane Flight. Safe at What Age?

Dr. Warren: I am expecting my first baby in mid-June and I am currently scheduled to attend a conference at the end of June that would require travel by plane. Is there a time when it is too early to take an infant on a plane? (I do realize that I may not be ready to travel!) If technically it is ok, can you suggest any arguments against it? (One colleague was told some years ago not to fly too early with her infant because the tubes in their ears would not be fully formed.)

Thanks in advance!

-AG

Dear AG: The main risk to newborns flying is exposure to crowds, and therefore, infectious diseases, in the airport and in the closed space of the airplane. For this reason, I generally recommend avoiding flying with infants before 8 weeks of age.

All infants have a greater risk of ear pain and ear congestion than older children and adults. This can cause pain during flight. Infants have a higher frequency of ear infections than older children. Flying with an ear infection carries the risk of acute pain and rupture of the ear drum. Infants who fly with upper respiratory infections should take a decongestant drop like Neosynephrine or Afrin prior to the flight.

Sincerely,
Dr. Warren

Nursing 19 Month Old Gaining Weight Poorly

Dr. Warren: My son is 19 and 1/2 months old. He weighs only about 21 pounds and has gained little or no weight in a long time. His physical and mental development seem normal for a toddler. His motor skills are fine and his vocabulary is large for his age. His appetite is poor and he is often uninterested in eating. We offer him a variety of foods although he is a vegetarian. He still breastfeeds quite a bit for his age.

He gets a lot of colds and flu and his immune system seems to be weak. He has had all his vaccinations. His parents don't smoke. We are concerned.

Can you offer any suggestions.

Thank you.

-HG

Dear HG: If a 19 month old spends a lot of time nursing, doesn't eat, and has stopped gaining weight, it is likely he is choosing to nurse when he is hungry rather than eat, and that he is not getting enough milk to sustain his growth. While breast milk is excellent food, it was not intended to continue forever. While there is no need for mother to stop nursing, if you want your son to eat food, he has to spend less time on the breast. A high calorie supplement such as Pediasure may also help to get his weight gain started again.

At 19 months, your son should be having regular checkups which include an assessment of his growth. What does his pediatrician say?

Sincerely,
Dr. Warren

Appropriate Bed Time. Two Households

Dear Dr. Warren: I would like to know what is the best time for a 5 year old to go to bed. I am having problems with my ex-husband regarding a suitable bed time while she is with him. He feel's she should be able to stay up late (10:00 p.m.) on the weekends. Do you have any literature referencing suitable times for children her age?

Thank you.

-JG

Dear JG: 10 PM is a late bedtime for a 5 year old, but it is not inherently wrong or harmful. It depends how the child is spending the time and whether or not she sleeps late the next day or gets enough sleep at some point while she is with her father. What is most important is for children to have a routine. When children live in more than one household, it is easier if both households have the same routine, but if the routines are consistent in each household, there's no reason a child can't learn to have one routine at Mom's and another at Dad's. If Dad's schedule is such that the late bedtime on weekends permits him to spend time with his daughter, that precious time warrants a disruption of the regular routine. If the late hours before bed are spent vegetating in front of a TV watching inappropriate material for her age, your daughter would be better off having an earlier bedtime.

You need to assess what, if any, problem the 10 PM bedtime is causing for you and your daughter rather than looking to an arbitrary standard. If there are problems, try to find solutions that all of you can live with. This is not worth turning into a battle with your daughter caught in the middle.

Sincerely,
Dr. Warren

CT Scan for Small Head

Hi Dr. Warren: My son Steven is 1 year old, and his Dr told us his head is remarkly small (16.75 inches) and did not grow in last three three months. She suggested to do CT scan. May I ask you several questions about this
(1) Is this very harmful to the development of brain? Steven is 100% normal now. Will the head grow in a later time?

(2) Steven did X-ray in last Dec and it is normal. Is it harmful to do second X-ray exam in such a short time?

(3) If CT result also shows normal, what causes his small head and will it a problem for his intelligence in a long term.

Thanks.

-Steven's Dad

Dear Dad: If your son's head is small because your son's head bones are fused and the skull can't grow, this is dangerous to the brain and requires surgical correction. The condition is called craniosynostosis, and the CT scan will tell if that's what's going on.

If your son's head is not growing because his brain is not growing, that's not good either, but then the problem isn't the head size. It's what's going on with the brain. If your son's development is normal, that is an unlikely possibility.

If your son's head is small because your family tends to have small heads, that is just his normal growth pattern. If the CT scan is normal, his natural head size will not affect his intelligence.

Unnecessary x-rays should not be done since the effects of radiation are cumulative over a lifetime, but the dose of radiation in modern x-rays is very low. There is no danger in doing a CT scan now, even if your son had an x-ray 2 months ago.

Sincerely,
Dr. Warren

Milk Allergy Symptoms

Dr. Warren: I am an 18 year old college student. Around thanksgiving I noticed that my throat and stomach would feel funny after eating. This happened during the week but not on the weekend, I figured out that this is because I eat in the cafeteria during the week and drink milk, often times two glasses, but on weekends, I would eat at restaurants and would drink other things. The symptoms would be a queasy feeling in my stomach, and my throat slightly swelling up. This has now carried over to when I eat ice cream and large amounts of cheese, like three grilled cheese sandwiches. Is this lactose intolerant or an allergy to milk? I have temporarily solved the problem by avoiding dairy products, but this can't be a long term solution obviously.

Thanks.

-Eric

Dear Eric: Lactose intolerance is caused by an inability to digest lactose. It is not an allergy. The symptoms of gas and diarrhea occur after the milk gets into the intestines. Throat swelling and nausea are not symptoms of lactose intolerance. While nausea is not a specific symptom, throat swelling is a serious allergy symptom. If you are allergic to milk protein, you may have no choice but to avoid it for the rest of your life. Consult your doctor about having a RAST test done to see if you are allergic to milk. Since it may not always be possible to avoid milk protein, or even know when you are being exposed to it, you should also discuss the advisability of having emergency treatment for serious allergic reactions with you at all times.

Sincerely,
Dr. Warren

Lactose Intolerance Due to Intestinal Virus

Dr. Warren: My 9 month old had a stomach flu for several days, and after being off formula for those days become somewhat lactose intolerant. He would drink his formula at half strength, but if it was 3/4 or full strength he would throw it all up. I switched him to a soy formula which he takes at full strength with no vomitting. He has been on the soy formula for a week now, and for the past two nights has awoken with severe abdominal cramping. Is this caused by the soy formula? He has had some diarrhea, but not every stool. His bowels are working, and he is hydrated. Should I switch him back to the regular formula? Should I start by mixing the two to slowly introduce the lactose back into his system? I have read that occasionaly with a stomach flu the child can become temporarily lactose intolerant, but I didn't find anything that indicated how long it might last. I would appreciate any advice you can give for I have stumped the pediatricians in our area, and I'm feeling frustrated and helpless. I am very concerned about the abdominal cramping, so anything you can come up with that might help to ease his pain would be very greatly appreciated!!

Thank you so much.

Sincerely,
-LR

Dear LR: There is no standard length of time that a child remains lactose intolerant after a bout of gastroenteritis. The more severe the intestinal virus symptoms, the more damage it does to the intestinal lining, and so the more severe and persistent the lactose intolerance will be. Lactose is not digested in the stomach. It is digested in the lower intestines. The symptoms of lactose intolerance include gas, abdominal pain, and diarrhea. Vomiting may occur in response to the cramping, but if it occurs immediately after the feeding, it is more likely due to the stomach still being upset by the virus rather than lactose intolerance.

Most patients are fully recovered from an intestinal virus within a week, but sometimes symptoms, including cramping, can persist two weeks or more. The soy formula is unlikely to be causing cramping, but in the unlikely event that even the soy is contributing to symptoms, you could try a hypoallergenic formula like Alimentum or Nutramigen. You could also try going back to your son's regular formula, but there is no rush to do so. I cannot predict whether he will be symptomatically better or worse on his regular formula.

If your son is ill with high fever, has persisting diarrhea, or has blood in the stool, you doctor should do a stool culture to check for bacterial infections. While gastroenteritis can be a frustrating illness, as long as your child remains well hydrated, he is in no danger, and the illness will pass. If it persists and the stool cultures are negative, then you should consult a gastroenterologist.

Sincerely,
Dr. Warren

Vomiting and Bad Breath

Dear Dr. Warren: My child had tubes put in her ears a week ago. She has had a bad problem with vomiting. The doctor said her ears were real bad and that the tubes were just what she needed. She still has a problem puking and her breath has a foul smell. She also had her adenoids removed. She is 2½ years old. Should her breath smell so bad and what could cause her to puke so much. CAT scan and scope next week.

-SR

Dear SR: There are many reasons why a child may vomit. The CT scan and endoscopy scheduled for next week may provide some answers. The foul smell of your daughter's breath could be related to the vomiting. She may have acetone on her breath from vomiting a lot. If that's the case, she should also be checked for diabetes which can cause vomiting and acetone on the breath. Since your daughter had enlarged adenoids and chronic ear problems, she may have a sinus infection which could cause bad breath and vomiting. The bad breath could be caused by debris in the crypts of your daughter's tongue aggravated by the vomiting. If so, cleaning the tongue would help.

Sincerely,
Dr. Warren
