My 5 year old's behaviour I feel is so out of control. She is constantly smacking, hitting and kicking me and her 2 younger siblings. She says things like 'you're not even pretty' and 'if you don't do this for me I'm going to hit you'. It's awful and I've no idea where it's all come from. Any ideas how to discipline this type of behaviour please? She is also a serial liar and getting other people into trouble about it. She lies about school and what her teachers say, she screams at me to do her homework for her. She wrecks her toys, I am embarrassed to hang out with my friends anymore because she is such a bully to others. Please any advice would be appreciated. I'm worried I'm going to be evicted from my home because of the amount of screaming she does due to her tantrums. I'm a single parent with no help from their dad or my family.
