My 16mth old son seems to be petrified of other poeple and not just strangers . The only people he's comfortable with are myself, his dad and 1 of his grandparents (she looks after him twice a week while I work). As soon as he sees other members of my family and my husbands family or any friends he screams, gets extremely upset and is inconsolable. This has been happening for 2-3 months now and it's really upsetting me. The only way he stops is to leave him on his own with his favourite dvd on! There is no pattern whatsoever that I can see as to who he cries at. Any advice please?
