My 3 year old ds is.very socially awkward. He doesn't really know how to play with other children without some guidance from adults. He wants to play., but a lot of the time he stands on the sidelines looking at the other children. Another thing is he is really nervous If we are somewhere and we go out of his line of vision. A play therapist wad recommend to me to help him. Has anyone any experience with this? Did it help?
