My son is 10 years old and in the 4th grade. He is an only child and is very well adjusted, he is just a very happy kid. He has always had friends that are girls, but never had any boys that he does stuff with other than sports or other activities. Should I be concerned? We have, as a family, moved quite a bit...kindergarten in Chicago, 1st grade Canada, 2nd & 3rd back to the States close to extended family, 4th another school...he does make friends easily, is confident and secure, the teacher said kids like him but no boys ever at get togethers, just girls. Doesn't seem to bother him but should it?
