DD2 has just turned 2 and she's increasingly aggressive. I know this is normal for this age, I went through it with my first child, but I feel exhausted by it and its getting me down (my as my eldest didn't come out of this phase really until 3.5!) So today, for example, she ran up to one of those ride one in the supermarket and hit the kid who has already in it because she wanted a go...the mother was lovely, I was truly mortified, pulled her off to the side and told her no but then they left so DD got her turn (in hindsight I should have left and not let her have a go even when it became free)...then later at a cafe a little boy came up to our table and DD2 went to hit out at him and shouted (I think because she thought he wanted her sandwich!), again I was mortified, apologised to the mother etc. I'm a SAHM & she doesn't go to nursery but I'm starting to feel like I need to avoid playgroups for a while as I just gave to follow her around making sure she doesn't hit anyone. At playgroup I tell her that if she hits, we leave, and I do follow through with that. She's always hitting out at her big sister, I tell her no, separate them, take the toy off her etc but I feel like I'm getting nowhere & that everywhere we go has the potential for being unpleasant :( what more can I do?
