Me or my other half are not child minded at all, but I have to say, In MY OPINION, thats child abuse. Unless their is some kind of restrictive disability, their is no way a nine year old should bathe with someone else, or sleep with someone else. Thats Not Right!!! Its tough though, maybe try talking to the little guy. See if he mentions anything he isnt happy with. Id definately ring social services to see what their view on the matter is. I think you have a duty to do something! :-)
