in foods that are known to make kids hyper! ds1 had frosted shreddied for breakfast and then proceeded to run around like a lunatic for about 3 hours!!!! - whenever i got hold of him he was shaking he was that hyper! he is like this with alot of foods but i have done my best to cut out E numbers what else do i need to consider - he dipped his little finger in the sugar bowl at my mums the other day resulting in the same behavior! is that normal?
