My DS is 12. Has been friends with this bit, let’s call him Oliver, since toddler group. I’m friends with his mum, not close friends but we do socialise occasionally. Dos and Oliver both moved to the same school last year. They were friendly to begin with but Oliver is now in the ‘in’ crowd and DS isn’t. Oliver seems to be making a low-level campaign against DS. If DS sits at the same lunch table Oliver gets up and moves and takes his mates with him, on occasion leaving DS sitting on his own. He’s telling people DS is weird, annoying, lazy, crap at sport etc and DS is finding other people he thought we’re friends are now pulling away from him too. Do I speak to Oliver’s mum, or do I speak to school? Or do nothing? Is this normal adjustment of friendship groups? I’m thinking it is verging on bullying but I worry I am overreacting. DS is crying in bed and I’m absolutely raging at Oliver, so I need some perspective please fellow MNers!
