Dd is 22 mo & a generally happy sociable child. She is an only child at present.
There is a younger boy at the CM's and she pushes him once or twice a day when he is in her way etc. I think she is possessive of the CM & and is jealous when he gets attention. He is a lovely 15mo. I work PT and she goes 3 days/week. I have tried explaining why not to do it etc but it's not really making much difference.
Any advice ??
