My son had a reaction to the child shots. That didn't stop me from having him immunized. They ended up giving him the adult one, but had to have a lesser dose more often. He was a very hyper child & the Dr put him on meds for this. I did not like the reaction he had on this med, made him like a zombi, so I got to checking things out & found that taking away any foods that had artificial coloring, flavoring, sugar, additives & preservatives totally turned him around. It was almost impossible to find products at the store with out any of these items in it. So I made everything from scratch so I could control what was in them. It was so much more work for me, but well worth it. His teachers, at school, could hardly believe the difference in him. Believe me when I say that a lot of problems are caused by what is being added to our foods.
