In my policies, it states that I need 24 hours notice if someone other than mom or dad (or other person I know about) is picking up the child. If it is an emergency (my husband suggested) they text me a picture of the person who is picking them up, or give me their name and date of birth and I check for ID at the door. There is NO WAY I would release the child to someone I wasn't told would be picking them up - even if I'd met them before. You never what goes on in these families....
