Please if anyone can provide me with any links or information on how certain food dyes or additives can affect a childs behavior. I would be very appreciative! I have a very hyper active 4yr old, who I feel has sensetivities too food colorings and such. But so far have been unable too convince my husband of this. He is a very bright mischevious boy. Which while it makes him a hand full, also makes him a joy too have around. But he also has an out of control side that makes him impossible too deal with. I let him have cherry Kool-aid today. And too make it worse it was on an empty stomach. He had ben behaving rather well but he suddenly just went out of control. I was trying too do a friends hair and he just started acting out something awful. His sister was sitting on a small chair in front of the door, he just walked up too her and for no reason grabbed a handful of hair and slammed her head back against the door. Then before I could even react, he did it again!!<img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/yikes.gif" style="border:0px solid;" title="EEK!"> This has too stop. I'm afraid of him hurting himself or one of his siblings. This is the same child who wants too hug and kiss his baby brother all day. Its not his normal personality, too be mean like that. But I have too convince dh. Please, any help or advice would be greatly appreciated! Thanks!
