I'm desperate for help and just don't know what to do. 8YO DS has always been an easy child. He does well at school, good friendships and a happy home life with no behavioural problems. In the last 3 weeks he's turned into a child I don't know. He's rude, argumentative and turning violent. Hes refusing to go to bad and acting appallingly at bedtime. He's screaming, throwing things and saying he hates us and hates life. Twice in the last week we've had to physically restrain him as hes trying to hurt himself and tonight he punched DP. It's taken two hours to calm him down.
I'm lost, I don't know this child and how to parent him and need help. I try to talk to him in the calm of day but he says nothing and makes lots of promises but always ends up creating issues. This week we ordered something he'd saved for but said we wouldn't pick it up unless his behaviour improved. He was much better for two days and today we got it and hes been horrible again tonight. So he's able to be good.
I feel like he's manipulating us and we're on eggshells and dreading the evenings. Hes acting like a caged animal on his knees growling at us and lashing out. Hes using language we don't use so I guess picked up from school but only just started using it.
For info he has limited screen time, no unsupervised internet access, a Nintendo switch with limited time and no online gaming. He eats well and has a balanced diet. Hes always been an early riser but until a few weeks ago has gone to bed with no issues. Bedtime is 7.30 weekdays 8 on weekends. Apologies if not relevant just wanted to give as much info as possible.
I know I need help but who from - is it GP, NSPCC? Any help very much appreciated
