My son (6) was at a friend's house for tea recently. Apparently they played beautifully but towards the end there was a scuffle which ended in the other boy crying. I've asked my son and he admitted they'd been shutting each other in the cupboard and ended up 'wrestling'. My concern is that the mum said my son held her son's nose. I've asked him and although he admits to everything else he's adamant this never happened. We've had a chat and explained how dangerous that would be (although he still denied it). The boy is coming for tea at our house this week (so mum isn't too concerned) but I'm still worrying about this. Should I be concerned? I'm still streesing as recently he has done a couple of things that are out of character and wonder where/ who it's coming from.
