DS 13 (asd) today threw a massive tantrum/meltdown over his homework. He was given maths homework last Friday which he hid from us. Sent home to do on Monday -refused. Tuesday he took back his phone (which he'd lost for the day because I found it on the floor amongst his Lego) whilst I was out taking Dd to her music lesson and used the calculator. He promised yesterday to learn his vocab today, and today refused, saying he'd agreed to meet some friends to play. I said he had to do it before going out and reminded that he had promised to do it today. After tantrumming about how unfair life is for 2 hours, kicking his school bag around etc he said "I'm going out" and walked out to meet his friends.
He didn't do anything stupid outside and he stayed within bounds. Realistically, he is much stronger than me and my size. I couldn't have stopped him if I'd tried.
How are you supposed to deal with this situation. He is currently in his room, refusing to tidy it, have a shower, finish his homework...
