DD is 2.6 and quite simply, apart from one little boy in particular, doesnt seem to like other children!! BY this i mean that when we go to groups and stuff she will stick to me like glue, moan and grimace when other children approach her, keep other children at arms length (sometimes) and generally plays lovely on her own but will throw her rattle out of the pram (literally!) if another child tries to join in. How can I make her more sociable????
