I am beginning to think I am paranoid, but I have thought for some time that my sons friends mum is going around badmouthing me and my son to other parents. I have tried to create some distance between the kids anyway as they had formed a trio, with my son often being a bit of a third wheel and sometimes being outright excluded. There has been a class reshuffle and the other two kids are in one class, my son in the other (kids are all six), but my son still gravitates towards them. I feel that the mum hates me and is trying to alienate her daughter and the other boy in the trio against my son, as well as other parents from both classes. This whole thing has been going on for about five months now, with the reshuffle happening just now. I am aware I probably sound crazy, and sometimes I think this is ridiculous, if the kids want to be friends I have to support it and also sometimes the mum is nice and I wonder what I am doing. I just don't know what to do as my son keeps asking for playdates with this girl. The girl also wants to, but I'm worried they will just begin excluding him again so would prefer him to find other friends in his new class. I also don't know how to deal with the mum, I feel it has just become so awkward a of it. I would be really grateful for any advice. Thank you.
