I'm at my wits end with his behaviour, I know I'm managing it wrong but I don't know what to do. My boy can be so lovely but every night when he comes home from school he goes into this really naughty stage, he'll break things, hit and nothing works to avoid a meltdown. It's like he deliberately pushes me, mostly I keep my temper and let it play out but sometimes it pushes me until I shout at him, then I feel awful but I can't cope with it. No punishment, talks, cuddles seem to help, what can I do?
