help please, I don't want my dc to become a bully

[DiddleAndGruff]

I know this is a common problem but I don't know how to tackle it. My 5-year-old ds is infatuated with a couple of boys in his class who, I believe, he has become rather possessive of and leaves out his other friends. One of them is now very upset and I want to nip this behaviour in the bud before it goes any further. But my ds does not seem to have much empathy and is hard to talk to about feelings etc. I am not sure he really gets it when I talk to him about how to behave with friends. Is that normal for a five-year-old? I am a worrier and am now fretting that he will turn into a bully but I actually have no idea how to talk to him. Anyone who has dealt with this situation I would really appreciate your advice. thanks

It sounds within the normal range of friendship travails (so not embryonic bullying).
You could do everything to strengthen his friendships with other children to offset some of it. I'd speak to the school about it all, otherwise; it's happening in school time, after all.

Thanks peanutbutterkid, just concerned that it may escalate or that he is being mean to kids and I don't even know about it.
