I have dealt with constant sibling bickering, whinging, shoving etc by ignoring it- so long as its 50:50 - this has done the trick and they have really settled down. Also have made ds1's room total no-go zone for ds2 which has def helped with anger issues of ds1. What do I do if either one commits and complete no-no (biting,hitting, anything I know they know if not on). Please don't say naughty step /timeout of stickers. Looking for a really imaginative but simple idea as ds1 really just doesn't get it sometimes- like last night he wasn't allowed cartoons coz he didn't get into the bath - this morning I realised he thought the ban was forever, bless him.
