My DD3 has just started to push my 1 yo over and do things like grab her on her wrist and pull her. At kindy DD3 is taught has been taught to keep her hands to herself, so I just ask her to keep her hands to herself. However, when doing this I get up close to
DD and look her in the eyes. I also ask her why she has pushed/pulled etc and I try and get her to verbalise her actions and reasons. Then I mediate and explain to
DD that dd2 is only a baby and doesn't understand. This seems to be working, I just keep my actions consistent.
