Question about children interacting with other children with vaccinations

I have a question and would really appreciate if anyone has any feedback. I have done a breif research on vaccinations and have made the chioce to not vaccinate my two children who are four and five now. My question is (now that my oldest will be attending school next year)will they be safe around other children that have received shots?? And how safe are they around Babies?I babysit for a baby that will be getting shots next week and need to know if i should have the mother find alternate care for a while? I just have not been able to find too much info on this topic and would really appreciate some feedback. Thank you:) Tweet
