I am a Childminder and every wednesday my mother comes over to spend some time with my son whilst I mind the other children. Every so often my mother-in-law pops over to spend some time with my son too. My mum stays most of the day and we may pop out for a walk with the kids or go to a baby group, my mother pushes my son in the buggy and I'm always in charge of the other mindees, never leaving my mother alone with them (not that she can't be trusted!) I was just wondering, does she need a CRB for being around the mindees on days like this or is signing in a visitors book enough?
