I am at the end of my tether with my 4 year old daughters behaviour. She has always been defiant (starting with a difficult birth), but lately seems to be out of control eg breaking things, hitting her 18month old brother and me, screaming when she doesn't get her own way - this happens every day. Of course, she's good at playgroup.I've tried everything including star charts. Everyone tells me she'll grow out of it, but they've been saying this since she was 2! I feel I have no support as my family don't live nearby and my husband works all hours.My mum even downplays the behaviour saying she's a 'pickle' - if only! I'm now 2 months pregnant with number 3 and am worn out with it all. Anyone have any ideas/help??
