My DS is struggling a bit with feeling lonely at school and I think he would benefit from joining some groups where he might meet more like-minded people. He does have friends but as they're getting older the differences seem to be creating a bit of a barrier and the friends he has are preferring to spend more time with other kids who aren't so bossy/rigid in their thinking.
For context: he's 6, into maths, space, puzzles, riddles. No interest in team sports but he is active and enjoys p.e./swimming/gymnastics. In general he connects more with adults/older children.
Can anyone suggest any clubs, groups or activities which might be worth a try?
