DC (age 6)won’t talk to adults unless he knows them very very well. He’ll talk to adults in the family only (mummy, daddy, grandparents, uncles and aunties). He won’t talk to his teacher unless she asks him a direct question. He won’t talk to neighbours at all. Not even hello goodbye yes or no or a wave, even if they talk to him directly. Same with previous teachers or headteacher or any adult who he would know but non family. It comes across as very rude when he won’t say hello or goodbye even if they talk to him directly. I’ve told him he can wave if he doesn’t want to actually talk at least that shows some acknowledgement but he won’t do that either. He is very chatty and sociable when playing with children and within our family. Has anyone else had this? My concern is firstly it comes across very rude, secondly if he needs something he doesn’t ask a teacher or adult for it. Any ideas what might help him develop this skill a bit?
