I'd rather him not learning it the hard way by losing all his friends...
He's 4.5, in reception. He's a bit of a stickler for the rules at times, and the oldest sibling in our family. So part of it seems to be that he genuinely believes rules should be obeyed (when he agrees with them), and part of it is clearly a power trip.
At home he's started constantly telling us about his sister doing this and that, it got really worse since September. We essentially tell him to mind his own business, and that we are the ones responsible for parenting and not him.
But I'm more worried about the fact that we've seen him doing similar things with his school friends, and some are getting annoyed.
We're trying to find a way to tell him that he shouldn't be afraid to tell someone about something that could be dangerous for instance, but that he shouldn't be constantly watching over his friends' shoulders. Particularly when it's because he find it funny when they get in trouble...
We can't really find the words... Any clever ideas?
