Ds 10 has been out of sorts for quite a few days grumpy,huffing & puffing when asked to do anything or arguing about it, withdrawn ( I don't think he's being bullied) I've asked him what's wrong, if there's anything he wants to talk to me about. He has said no, but yesterday as I was on my way out ( so didn't have chance to talk about it) he came to me & said he feels angry all the time and with everyone. Is this normal, is it hormones?
