Hello everyone. My son is turning 3 this month. He's my youngest, and oh my god, his behaviour is horrendous. He kicks my oven and kitchen doors in temper, he's forever hitting my middle child (his sister) he rips her glasses off her face and throws them or pulls them trying to break them he throws everything, he tries to hit me some times (not all the time) he's drawn all over my walls, he shouts and screams at me at home or out in public. He point blank refuses to listen to me. If anyone tells him off he just laughs at us all. I'm at my wits end. I don't know what else to do so I've come on here for any advice and tips please. TIA x
