5 year old accused of bullying

[catandgirlmum]

My eldest DD is 5 and in year 1 at school. She seems to have a few girl friends she talks about regularly which is nice. Occasionally I hear about the odd fall out they have 'so and so said I couldn't play with her today' etc. But I vaguely remember this when I was in school with girls bickering and falling out one day and BFF the next so don't take it too seriously.
Yesterday she came home from school and said 'mummy X told me today that her Mummy said I am a bully, what's a bully?'
I explained to her as best I could what a bully is and I know none of us want to believe our child could be capable of bullying but truly knowing my DD and the fact she's only 5 I really cannot comprehend why anyone would think she is a bully. I asked her why she would think this and she said she didn't know.
I have no idea if X was telling the truth or not and whether her Mum has actually said this but it just doesn't sit right with me.
Today I asked her who she played with at lunch time she said I was playing hide and seek with X but she ran away from me and hid (with two other girls in her class) so she found someone else to play with. She didn't seem bothered about it and was still cheerful this evening. But it just makes me feel so sad. Is this normal girl friendship behaviours for her age? I'm sure I have worse to come the older she gets :(

If your DD is unbothered by it, and you know very little details about it, I wouldn't spend too much time worrying about it tbh

It actually sounds like the other girl may be a bully and she’s learnt that from her toxic mother. Accusing a 5 year old if bullying is very unkind.

I would speak to the teacher and try to get this nipped in the bud.

Kids repeat what adults say.

You don’t seem to know the other mum?

I wouldn’t over ask in these situations as they tend to blow over, however it’s a sharp learning curve that you discover some adults really are the pits.

I have been debating whether to speak to the teacher about this but then argue with myself that I could potentially make things worse for her or be causing a mountain out of a molehill and then be labelled as a fussy Mum (can you tell I'm an over thinker?!)
If this Mum genuinely believes my DD is a bully she should be speaking with the teacher about this and I would happily go into the school for a meeting and hear them out on why she thinks she's a 'bully' but instead she's egging her DD up to call her a bully (which my DD didn't even know the definition of but did know it wasn't a good thing to be called!)
I think unfortunately the word bully these days gets thrown around far too much which then makes it have less meaning for children/adults who really are being bullied.
Thanks for the advice. It helps to hear others perspectives.

Exactly I try not to over ask and let her come to me and tbf she rarely seems to have issues in school just the odd mention of a falling out here and there which I think is just normal childhood development. She is happy in herself and I think she's still young enough to think 'if they don't want to play with me I will play with someone else' and it not effect her confidence.

Also she won an award a couple of weeks ago at school and on the certificate it said what a lovely and kind friend she is, always helping others in her class and smiling. So I'm just so shocked she's come home this week saying someone's mum has called her a bully :( and then having the explain what that means to her was really difficult.
