Is there any point in bringing this up? What could I ask them to do about it?
I know a long list of things I can try to do to change things, (but they may not work).
DS (y2) used to have a strong friendship circle.
He says he quite likes just playing on his own (that he mostly plays alone confirmed by older DD at same school).
But I'm afraid that he is vulnerable without a "gang", loners are always vulnerable to bullies. :(.
