I have four children, my last has autism. Don't know how it happened but it did. All of my children have had their shots, with the exception of my oldest who didn't get his chicken pox shot and promptly got the chicken pox about a year after my youngest was born.
Would I like to know what caused my child's autism? Sure if it will help him and prevent other children from being afflicted.
Is it a driving need for me to know how this happened to my child? Not really, I'm more concerned with the now and getting Joshua the help he needs.
