ok, my son has recently picked up some very mean things. Not swearing or anything, but theres this smirky face when being told off (thinks being in trouble is funny), and responses like "I'm not going to be your best friend anymore" "I'm not going to play with you now" or "I'm not listening to you" (and turning his head away).
Has anyone else experienced this with their child and how did you over come it? I don't know how to respond to such behavior...
