Hi and welcome. Yes what all the others have said!

About the food allergies, my oldest Ben is definatley allergic to dairy. It does not show up on tests though, but like the allergist said it doesn't necessarily show on those tests but his body definately reacts to it.

I noticed his behaviour really early on and switched him to soy formula, actually did that cause of stomache upset and then realized that he was a totally different baby.
When it was time to put him on real milk, we did and then had a hideous screaming monster on our hands, we are talking biting, screaming, hitting. I used to say he hated me, the world but worst of all himself when he was in that state.

I pulled him back off the milk and put him on soy milk and tried to avoid dairy of any kind and voila! lovely little boy again.
He doesn't have a physical reaction to it like hives or diarreah but certainly mentally it alters him.

He tries it occasionally now and then and it still makes him miserable. He can control it a lot more now as he is getting older.

I say it's worth trying your son on a dairy free diet for a bit to see if there is any change. It's a pain in the butt I will tell ya! There is dairy in everything!

If you decide to, feel free to send me a personal message and I'm happy to help you out.

Good luck!
