My opposite sex twins are in year one at school. They are popular and well known in the school but neither of them have a wide circle of friends. In fact they very seldom play with anyone in their class other than each other. My DD (the dominant and more advanced twin) tends to play with older boys and my DS (approximately 9 months behind his peers) has one close friend but prefers to play with his sister. They are each other's best friend which is lovely, and they play together beautifully but it is sooooo important that they have friendships outside of their own relationship. Today at school my daughter asked several girls to play but they all said no. Partly this was because she asked them to play her game rather than joining them in their games but I am concerned that they are beginning to consider our kids to be antisocial because they only play together. I think that she is starting to fear the rejection she feels when her school mates say no. We do play dates reasonably regularly but often they just seem to play with each other during those too. Does anyone have any similar experience?
