Ds5 is in reception. There are a couple of boys who have taken to calling him monster (in the frame of them playing tag and him chasing, but also while not playing tag). They are friends and not being particularly mean or bullying, just playing.
Ds is my eldest, and is very like me - insecure, lacking confidence and resilience. He doesn't like being called monster, but won't say anything about it to the boys. Me and dp have separately explained he can tell them not to call him that, but he won't.
I chat with one of the mums every day at pick up, she's friendly and nice. Do I mention it to her? She's quite strict so I've no doubt she would act on it, and not take issue with me. Or should he be learning resilience/how to deal with things like this himself? He's a very sensitive child, I don't want him to suffer, but I do want to help him grow (and not be picked on because his mum fights his battles!!).
