I don't even allow diapers bags. Way too much stuff not meant for babies get kept in diaper bags. Plus a provider friend of mine had a bad experience with a family putting a recorder in the daycare kids diaper bag and recorded her all day. She didn't do anything wrong and the family had no reason to suspect anything, they just did it. She termed.

I require families to leave a 30 day supply of diapers here and then I let them know to bring more when they get to the half way point.
