I mean the disorder of children being over-active. I think I heard about this from a doctor which is a very close friend of my mother. His son has its symptoms and he told us that it is because of the milk he took when he was a baby. The boy only took formulated cow's milk from the time he was born until now.

I can't find a source of this subject if it true or not. So please correct me if I'm wrong about this. I would really appreciate someone who would clear this up.

What exactly do you mean by over active, are you talking about being hyper active here? I am a little confused so I need some clarification, thanks.

I'm assuming you mean Attention Deficit Hyperactive Disorder (ADHD). It's possible that milk has a behavioral effect if he has a milk sensitivity, but if it's true ADHD milk won't cause that because it is a disorder in the wiring of the brain.
