I was wondering if you had found a solution to your problem, as you last posted in September. Have you thought about nannying services where one person would look after your child and maybe one or two more? They usually come to your home. That seems like a great choice for parents who are not vaccinating or are delaying/spacing vaccines. The problem with daycare for unvaccinated kids is that the likliehood of them contracting a vaccine-preventable disease is much higher, especially when rates of vaccination in your area dip below a certain percentage. Herd immunity, for instance, fails to protect the vulnerable when vaccination rates for pertussis drop below 85%. The higher the rates of non-vaccination in your area, the higher the risk your kid may contract a disease preventable by vaccines. In addition, daycare centers have a variety of ages of kids and also a diversity of kids with certain health problems that may not be obvious. For instance, severe asthma is treated sometimes with systemic corticosteroids, which suppress the immune system. These kids can't get certain vaccines and are immuno-compromised...a child that isn't vaccinated for, say, measles could infect them and they could become very ill.
I recognize the difficulty in trying to do the best for your baby while also living in a modern world where we must also find childcare. I would opt for the choice that not only protects my kid the most, but also doesn't put other people's kids at any undue, if not unforeseen and unanticipated, risk.
