Quick background: DS1 is 10. Eldest of 4 DC. He's a 'gifted' child acedemically - scoring over 95% in 11+ practice tests etc. He is highly logical with a huge 'justice chip' and obessed with things being 'fair'. Avid reader, robotics, lego and nature/animals. no interest in any sport. Good healthy balanced diet. School say he is polite, helpful, well mannered as do other parents when he has gone to play.
The issue is his behaviour/temper at home. For the last 12-18months it seems to be getting worse.
Examples: All DC have a daily tick list - a couple of chores along with the standard 'get up, get dressed, make bed' etc. Chores are on a rota so everyone has the same number of 'set up breakfast' 'empty dishwasher' 'do laundry' etc. it is completely fair and equal. Yet every time we tell DS to get on with his list he growls, huffs, scowls that its not fair. if he then doesnt do it and we ask him again to get on with it he starts screaming in our faces 'I'M DOING IT!' (when he's clearly not) or 'I DONT WANT TO!' etc.
He reacts this way to being asked to do anything that may consitute a 'job' or 'chore'.
Once he's in a temper about something he will then scream at anyone and everyone. For example if one of the other DCs come to ask me a question he will scream 'I DONT CARE!' at them or 'SHUT UP'.
We have a clearly laid out set of consequences - first they loose a token from their reward tube, then screens are removed for the day, then its go to bed early. we are very consistant with this.
It's like a red mist desends and he cannot calm down once something has set him off and he can wizz through all those consequences in minutes as he seems not to hear us or will not respond to us asking him to leave the room to calm down.
He has his own room which we have sorted with him to make it a nice private space and have tried to encourage him to take a break up there when he feels angry but once the red mist descends he wont go.
He can also be violent, hitting walls, slamming doors, growling and screaming in the other DCs faces. he will also lash out has his siblings.
DH and I are at our wits end with it. we are doing all the 'right' things - he gets one on one time with us, he has his own room, he has clear boundaries and consequences but nothing seems to be improving this.
Yet in between he is the sweetest, cleverest, most interesting boy. we joke often that he would be a perfect only child (as a lot of anger starts with his siblings and the perceived 'not fair' devision of work). When we have him on his own he is an absolute delight.
I spoke to his teacher who said it is likely to be hormones and puberty starting but part of me is wondering could it be signs that he has some level of autism? anyone had similar and successfully navigated it?
Help please!!
