Ds (13) is Autistic and has a lot of anxiety, particularly around school. I understand he has a lot of struggles due to this but he seems to take out all his frustration on his 2 siblings but mostly ds2 (10). They've never had a close relationship but recently he can't tolerate even being him near him. Anything ds2 says he has to reply with sarcasm or tells him to shut up. He says he hates him and hates living with him. He has sensory issues and hates that ds2 sings and talks loudly. I've bought him noise cancelling headphones but refuses to wear them.
Generally he's a well behaved and gentle boy but recently (teenage hormones!) he's become so moody, rude and stubborn with me too. I can deal with it (mostly) but I absolutely can't stand how he treats ds2 and the deteriorating affect it's having on the rest of us. It's led to ds2 getting angry very easily and crying multiple times a day. This then leads to DH (also Autistic) shouting and punishing ds1 which doesn't help the situation. Oh and DH has been having a go at me recently that I spoil ds1 and suggesting that I'm too soft on him and I let him get away with things. Ffs. I can't deal with any of them at the moment. But I know if we can somehow improve the relationship between both brothers then it won't escalate with everyone frustrated with each other. Anyone else in a similar situaton? Any helpful ideas?
