She's really rough with him, hitting him and pinching him whenever he picks her up (she's one). She does it to me too, but not so much, and at nursery they say they've seen her do it to dh but she doesn't do it to them and she's quite gentle with the other kids. It seems like she thinks its a game - she's smiling and laughing when she does it. My only thought is that he does a lot of 'rough and tumble' type play with her and so she thinks this is what he finds funny. At the moment he just puts her down and walks away when she does it (and she cries). Anyone else had this?
