I'm at the end of my tether. Two of my children share a room and the other is in the box room. The two who share fight all the time. I swear they would argue over the colour of a bloody orange. I try my best to stop them separate them etc but the moment I go to the toilet/shower they start again. To make things worse one of them is being assessed for asd and the other knows exactly the buttons to press to send him into meltdown. Its driving me nuts and to make things worse my neighbour just knocked threatening to call the police if they dont stop as he works nights. I just dont know what to do it's like they hate each others guts. I take their things away, separate them and they still carry on.
