My CM's DD bit my DD last week. I don't know exactly how my CM dealt with the situation. All I know is that my DD was playing with a pushchair at a toddler group, the CM's DD tried to take the pushchair off of her, my DD refused to let go so the CM's DD bit her. Obviously I'm not exactly happy that the situation was allowed to develop in the first place but what really bothers me now is that my DD is resisting being dropped off at the CM's. We saw the CM's DD today at church and my DD couldn't back away from her and hide behind me quick enough. I asked her why she didn't want to play with the CM's DD and she said "pushchair, my play" when I asked her what she meant, she said "round, round, up, down" (she was pushing the pushchair around a little slope and stair circuit) and then pointed to her teeth and the bite mark on her arm. She clearly is saying that she doesn't want to play with the CM's DD because of the biting incident. How do I approach the problem with my CM?
