I don't know if I should be concerned about this or not. There are two things about DD that are really starting to bother me.
First is that she has real trouble parting with her stuff. As in old stuff she doesn't use or show any interest in. Normally, I talk to her about it till I'm blue in the face, and she'd be a little upset, but not too bad. Yesterday, I gave her diapers away, and holy cow if she didn't have a meltdown! I didn't think to talk to her about it because they have been sitting around for months, and she hasn't even looked at the box. We had a long talk about babies who don't have diapers, and how she should have a kind heart and generous spirit, and she concluded that a) she wanted her stuff back and b) the babies should stand naked in the cold.
Which brings us to the next concern. She says mean things a lot. She'll talk about throwing people in the trash can (I'm likely to blame for that, since the rule is that things she won't put away go in the trash), about locking them out, cutting them with knives or scissors, hitting them, etc. When I ask her if that's a nice thing to do, how she'd like it if someone did it to her, she'll say that she'll do it to herself.
She is generally not violent at all, good with her peers, helpful, and polite. I don't know where this violent stuff is coming from, though.
