As far as immunizations go I don't ask and really don't care. That being said I did have a family who was the kind of family who never went to the doctor. I am not the kind of person who runs to the doctor over everything but there are some things that should be given antibiotics for. This particular families view was that given time the body will fight off whatever virus/infection on its own. It would be fine if they actually followed my sick policy and didn't bring the kids when they were sick. I ran into a lot of issues with the family - kids were always passing on their illnesses as they were always sick it seemed. It would annoy me so much when the dad would ask me what I think and I would say they should go to the doctor to get it checked out (especially when all other daycare kids have been away sick and are on antibiotics). Then they would never go. Poor kids would have to suffer. Of course they were told not to tell me they were sick either.

My concern would be that if a family is against immunization they might be hesitant to take the child to the doc when needed which could spread things around daycare more.
