My DD will be 5 in February her behaviour is out of control. She's constantly back chatting and screaming at me if she doesn't get her own way this happens a lot because I'm very stubborn and if I say no I mean no. At first it was just at home but now it's out in the shops too. I wasn't too concerned to begin with because I know it's a phase most children go through she knows her boundaries even though she tries to push them if I count to two she instantly does what I've ask (I.e goes to time out). She's a very loving beautifully natured girl until she doesn't get what she wants. She gets plenty of attention and affection from me she knows she's loved very much. Lately she's been acting out against her 20 month old brother this has me worried. She hits, kicks, bites and pushes him over. She tells me and him that she hates him and doesn't want him anymore, this is where I'm lost I have no idea what I can do to stop this behaviour from happening. My relationship with her father was physically violent towards me I believe 100% that this has affected and will affect her for the rest of her life that's why I finally left. I left 4 months ago and at first things where great she improved in every way possible until now. She begs not to have to go to her dads for the weekends, this behaviour has only started since she started begging not to go there. I just don't know what to do.
