DD is 5. since the birth of DS in june our relationship has changed a lot. we used to be very close. she used to hug me and say 'i love you' very often. that dropped down to virtually nothing. lately she has been screaming, shouting, hitting me, slamming doors, grunting, lying to us etc. mostly it's like she just has a switch flicked inside her. she goes really crazy. things that set her off aren't particularly provoking: i called the table in the kitchen the 'dining table' instead of just 'table' or i didn't understand a certain thing she said to me. today i picked her up from school, asked her calmly to get her cardigan out of her tray before we went home and she started shouting at me. other parents were shocked and commented on how terrible it was and i was quite embarrassed about some of the things she screamed at me. we have tried reward systems, time out, ignoring, giving lots of positive attention and one-on-one time and all the other positive parenting things. i've even smacked her in desperation, which i feel awful about. we realise it's all for attention, but we feel like we've tried everything and i feel so lost. i'm sat here sobbing as i type as i just want my little girl back who used to love me so much and tonight she shouted at me that she didn't love me anymore and it really hurt even though i'm sure she didn't really mean it.
