My DS is 9 (year 5), and is still having major temper tantrums, getting aggressive & hitting/kicking/scratching anyone within reach.
We did link it to computer games (posted here a few months ago), but it can happen for any reason.
I dragged him every step of the way to school this morning (did let go of his wrist long enough for him to put his shoes on at the end of the drive!). I'm not even sure what caused the explosion this time, but he was asked to stop reading & get ready for school, and that seemed to be enough.
Our current tactic is to ban screen time when he gets like this, but it hasn't really stopped him doing it.
Any suggestions, anyone?
