My 5-yr-old DC is in reception. He is very shy but has made friends with another boy who plays pretty roughly and - according to DC - says kind of blunt / mean things. (“you’re not a fast runner, I don’t want to play with you, you can’t have that toy for your birthday” etc). Dc comes home covered in bruises and says they’re from this boy and another, when they were “playing fighting”.
I spoke to his teacher about it and she said they have a good relationship and DC is happy 
I keep trying to persuade Dc to find another friend, but he doesn’t want to. Last night I had the friend over for a play date (curious to see what it was all about!) and the kid is one of those who thinks everything is “boring” etc, but didn’t play rough.
Anyway. DH and I have noticed that, since school started, DC has changed and has become less happy. He has such an ace Easter, and became his old self again. And now school and this crappy (maybe?!) friendship has started back up again, and DC is back to being whiney and unhappy again.
What on earth do I do?! We’re contemplating moving anyway, and this just makes it more attractive. If I could afford it, even though ideologically it doesn’t fit for me, I would consider private school!
