This is the second time it's happened, the first time was at his old school, where he became best friends with a little girl who was new.
They were upset when he left and it's taken him since January to find another close friendship, which he has now, but again, the other children are being really mean about it.
He keeps getting 'she's your girlfriend' type comments and all the children are telling him it was someone else who told them to 'pass it on'. 
It's so depressing. He told his teacher who spoke to them but they just carried on. It makes him upset and angry, and the little girl is also upset about it. He hates the idea of a 'girlfriend' and I understand this, he just gets on well with the girls and likes to play with her.
This is on top of some Y5 children who keep calling him names.
Is there anything I can do or does he just have to suck it up? Thinking of taking him out and HEing with his older brother tbh. but I don't want to give up on school especially when he has found a nice friend.
Any ideas or experience?
