I have been doing a lot of research about food sensitivities since dealing gluten-intolerance. When I got pregnant with my third child I was determined to avoid all of the potential triggers hoping he would not have the same problems as my other children. I chose to have a home birth to avoid hospital medications, interventions, and pathogen exposure. We avoided vaccinations and watched very closely as we introduced foods to my baby. And unfortunately, it hasn't done a lick of good.
Kaden had rashes all over his face for the first three months and has very sensitive skin. He has really bad eczema on his legs, feet, and hands and I have not been able to find the trigger. His stools are not normal. He was in the 85th percentile in weight and at 8 months he had dropped to the 25th. He is very active--but I don't think his activity could account for the huge drop. He does have the same gene sequence as his sister--two different gluten intolerance genes and no celiac genes. He reacts to gluten and milk with a flushed face, increased eczema, diarrhea, diaper rash, and evidence of intestinal damage in his stools, and sleep problems.
On the other hand, he has been much more easy-going than his siblings. He has a very easy temperament, was crawling at 5 months and walking at 10, and learning words at 10 months. It could just be a different personality, or that we knew what to watch for in food allergies so he hasn't had as much stress to deal with.
Either way I am disappointed that our lifestyle changes didn't seem to help even a little bit. The only other known potential trigger that I could not avoid was pesticide. We got chickens to eat yard pests, but the mosquito abatement truck still goes by almost weekly in the summer. I hope one day research shows why so many more kids are having autoimmune problems!
