If your dc is around other people and kids, he is being exposed to most of that stuff anyway. Babysitters you love are hard to find! I would stick with her and stop worrying. Most babysitters are around other kids (unless you have a full-time nanny), so they are all being exposed to childhood illnesses.<br><br>
I'm not entirely sure what her vax status has to do with it... she might be immune naturally to diseases, she might be vaxed but still contagious (pertussis), and she might never get exposed to other stuff. Plus, in my experience, most of the stuff that kids catch in daycare isn't a VAD. It's just some general colds, runny noses, etc.<br><br>
You can't control everyone your child comes into contact with, so the best you can do is keep your child's immune system as strong as you can, know he will get sick, and know he will get better.<br><br>
I guess something you might want to think about is why you only selectively vax your child, but feel more secure with a babysitter that is fully vaxed. What made you decide to vax or not vax for certain illnesses, and what causes you to feel better if someone else is vaxed?
