If you don't feel comfortable with the person then don't leave your bub with them, thats my philosophy.

DH and I AP and so far DS has only been left with his Nana and Grandma and thats it. We trust them to follow our ways of parenting. On one occasion I was going to leave him with a close friend who also APs but when I went round the day before to check she offered DS chocolate while I went to the loo, WTF! He was 4 months old.

You have be completely comfortable with the person. If you are not you will just spend the time you are away from Jazz worrying.
