Hi, my DS who is 4yrs behaves really badly when male friends come round to play, he snatches toys from them and screams and cries if they touch his 'favourite' digger, car etc...I try and prepare him beforehand by having discussions about how they let him play with their toys at their houses, and what it makes his friend feel like when he is rude to them...Am I expecting too much of him. He has a younger sister who is 2yrs old and we have the usual sibling squabbles but not as bad as when her male friend who is also 2yrs comes round to play...I think he sees him as a threat? Help anyone!
