Hi M.! My sister has six children...all ranging from newborn to seven years of age. She shares your view on vaccinations. She actually believes that the vaccinations her first child recieved caused some developmental problems with him. From what I remember the childrens "immunity" wasn't the big issue. Sure they got sick alot, but all children do. But what my sister DID have a horrible time with was the school system. She had to fight hard to get him in. I'm not sure how all that stuff works around here (my sister lives in Boston),
but its worth looking into to see what you're looking at.
Although my view on vaccines is different, I will say there are alot of mommy's out there who feel the way you do (for whatever reason). My sister is one of them. Just do what you believe is right for your little one and don't let anyone make you feel badly about it.
