My DS (18mo) has a lovely childminder and after a difficult settling period, seems to finally be quite happy with her. The only thing is, I've noticed he often comes home from her's with scratches on his face - once or twice they've been quite big ones. She hasn't said anything to me about them, but I wonder if I should ask her? She has another mindee - a 2.5yo girl, and my mum, who does the pick up, suspects this girl might be doing the scratching. This girl has been with the childminder on her own for a while and my DS is quite new, so it would be understandable if there was some jealousy there. I know at 18mo children get into all sorts of bumps and scrapes, but he doesn't really get scratches at any other time, and I don't like think of him being routinely "got at" by another child, if that is in fact what is happening - it might be something else I guess.
I really don't want to upset my childminder by bringing it up. What would be a good way to enquire without causing offence?
