Hopinso,
your story brought me to tears. Nobody should have to go through that once let alone 2 or 3 times. I am so sorry for your pain. Just remember....you all did what you thought was the right thing at the time.
When my son was a few hours old they told me in the hospital that he needed a hepB shot. I said "ok" thinking it was the right thing to do not knowing any better. A month later more shots, and more and more. By the time he was 15 months old he was almost autistic and had many many problems.
