DD is 2.5 with very good language skills. For a while now she's had a bit of an obsession with telling people to 'go away' in quite a cross way. I'm not sure where it's come from as obviously she is never told to go away at home! She says it a lot to DH, also to other children - if I ask her what she's done at preschool she will often tell me she said 'go away' to someone, and that they cried! She even gets her toys to say it to each other as she plays with them.
I know toddlers go through phases and she's just experimenting with relationships and interactions, but it really bothers me. I don't want her getting addicted to the drama of being mean to people, or to think that it's ok to speak to people like that. DH is also very hurt by it, though he doesn't let on to her. She just randomly says it to him whenever he walks in the room, which he tries to laugh off but it's quite upsetting.
Initially I was quite laid back about it, I didn't really respond apart from a brief "oh poor daddy / other child / toy" and modelling something nice to say. As it's gone on longer I've tried to clamp down harder on it but I'm also wary of feeding the behaviour with too much negative attention. She gets so much positive attention and is so showered with love, I just want her to be the lovely girl I know she is! Will she just grow out of it in time, or is there something I'm missing?!
