I'll try to make a long story as short as possible, while also giving all the important info. 2 of my children (the oldest 2; a girl and a boy) are consistently in the 90-97% for height, and 30-50% for weight, and 2 of my children (the youngest 2 sons) are consistently in the 5-10% for height, and the 3-5% for weight, or sometimes off the charts completely. It seems very odd to me that I would have 2 children that are in the 90-97% for height, and then 2 children who are 0-10% for height.
And that is not the only thing that concerns me. The 3 yr old (just turned 3 in Dec.) was also doing very well with potty training and then all of a sudden he is having bowel movements in his pants again. He has been potty trained since he was a few months over 2 years old, with maybe 1 accident per month up until about 2-3 months ago, but now its been rare (maybe 3 times in the last few months) to MAKE IT to the toilet for bowel movements. He has no problems what-so-ever with having pee accidents; just poop. He goes back and forth between diarrhea and constipation. Last Monday (1 week ago today) we were driving in the car and he vomited the oatmeal that he had eaten about 1 hour prior. It did not smell like vomit and was literally just undigested oatmeal. He did not complain of a stomach ache when asked, had no fever, but seemed tired the rest of the day, but otherwise healthy and ate normally. I thought the symptoms of constipation/diarrhea/poor growth/vomiting after oats, etc. sounded like he could have a gluten allergy or celiac disease, but haven't had him tested yet. I've had him off gluten since Tuesday to see if there was any improvement in the toilet accidents. I fed him gluten free cereal with soy milk on Sunday morning, and about 1 hour after eating, he vomited what looked to be just soy milk and the gluten free cereal he had eaten (not like when a child has an upset stomach, almost watery), and it didn't smell like vomit again. I have also noticed that he seems to be more tired than usual this last week or so. He has been under the care of 2 different pediatricians who have commented on him being under the charts and suggesting that I am not feeding him enough, but never suggesting that there could be any medical reasons for his inability to gain weight and height. He eats a lot for a 3 yr old in my opinion (sometimes 2 whole sandwiches for lunch) but he still can't gain weight.
He has a 3 year well-child appointment tomorrow, and I'm going to "push" his doctor for any ideas or testing we can do, and he has an appointment on Wednesday with an allergist to see if we can start some of the basic food allergy testing (scratch test). I hope I did a thorough job explaining my concern and his symptoms, but just to recap: small for his age, suddenly having poop accidents again, alternating constipation/diarrhea, vomiting after oatmeal (but not when he ate it in the past), vomiting after soy milk and gluten free cereal, seems more tired this last week or so (randomly laying down on the carpet or kitchen floor), no fever at all (even after vomiting), every once in a while was complaining of a tummy ache.
Do any of these symptoms sound like anything anyone on here has experienced, or had a child that had these symptoms? I need more to go off of so I can ask the doctor tomorrow or the allergist Wednesday to test him for specific things. Plus, I hate to see him "suffering" with any undiagnosed allergies, and I don't want him to have a permanent height problem if it's due to an allergy that we can fix. Please help.
