I fully delay fully vaccinating. My daughter started getting her vaccines very slowly at age 3 and will be fully vaccinated for Kindergarten at age 5. My son at 15 months has had no vaccinations.
My reasoning is that these vaccines are too much, too soon for their little bodies and being that they are home with me their exposure is limited. They are breastfed and protected in that way too. My reasoning for vaccinating is that I believe in herd immunity (although I disagree with the varicella vax) and NY does not really allow selective vaxing. My husband wanted our children vaccinated and this was a compromise we could both live with.
