I personally never wanted to shoot poisions into my children's bodies. We always treated out bodies the way they were made to be treated. We eat lots of real food. Lots of whole grains, veggies, fruits, ect.. Plus we take a good multi each day. It works. The Lord made our bodies to stay healthy if we treat it right. This Dec will be 13 yrs since I have had so much as a cold. My husband and children have gone about 6 yrs without one.
