My 4 year old starts school in 2 days and her behaviour is horrific. It's easy to say it's down to parenting but I've done nothing but do my best and try to teach her kind and gentle ways but right now she's being disgusting. She beats her little sister and hits me, her baby brother and her friends. She spits at people, calls them names, invades personal space, steals things, etc. The list goes on and I'm at my wits end. I honestly believe that at this rate she will get kicked out from school. How do you discipline this kind of behaviour please?
