Agh. This seems to have become my 3 yr old's catch phrase. Literally any time someone displeases him in the slightest, out comes the old friendship threat. It's becoming like an involuntary tic! He seems to use it at home at the moment (I asked nursery). Apart from it being really irritating to me, I'm worried he is going to start upsetting other children. I've told him we don't say things like that and explained why. What can I do? Will he grow out of it or do I need to call up my inner Supernanny?
(On the plus side, he has stopped hitting out at me in frustration - is 'you're not my friend', in fact, progress? )
