We are having behavioral problems with my 4 year old son. We have read of a red dye allergies in kids so we kept him off that in his diet and it has been working out pretty good. We had his eyes tested and they were fine. Were told bad eyesite in kids can make them agressive. Then my wife at work was given an article about yellow dye allergies uh never heard of that one. Well yesterday was a bad day for his behavior. For lunch he had cheeze pringles and that had yellow dye, and for dessert Toft Ice Cream yellow cake ice cream and it was yellow dye. He also had a ham sandwich so it was not all junk food. All afternoon he was agressive and not himself. So could this be the problem? I was also told by another person of wheat allergies this also new to me. I think the next thing we might do is to take him to see a pediatric neuroligist to get him tested for adhd. My 3 boys from the first marriage were adhd and my one son was ohd and adhd I hope these abbrieviations are right. We need to get this kid under control before he either hurts himself or his mother. She is short 5 foot and he is starting to beat up on her. Any suggestion out there? I am nervous about the testing for adhd because I have been told lately that any behavorial problems with kids they just slap this label on them and medicate them and I don't want to see this. Anyone else had these problems and can give any suggestion on what to do. You helped out with potty training so maybe someone can help me with this one. Thanks
