Are you for real? Or stirring?
One would think if you had such faith in the vaccinations you would not be concerned if your child was around children who are not vaccinated!
You are around people/children who are not vaccinated everywhere, not just at childcare. So if you want to keep away then maybe you should stay at home.
My children are vaccinated except for chicken pox. It actually does not even enter my head to think about other children's vaccination status.
I might add chicken pox went around my DDs preschool last year. The children who got it were all vaccinated. My DD still has not had them, although my older child has hence no need to be vaccinated for them.
