also what you are eating can affect children as well because in my young primary school days i was little s**t. I always getting into trouble and generally causing having havoc where ever i went, i got the wooden spoon alot

but anyway at some point i had alot of allergy testing done to me and it was found out that i was allergic to quite a few things but the biggy was MSG which can be found in alot of chips and that sort of stuff. After removing MSG from my diet i calmed down right down and i wasnt causing as much trouble as i was, and generally being a good little boy that i should of been.
