To call my child this?

[Ayemama]

Sometimes when my DC have been naughty or especially cheeky I call them a little poop because that's how they are behaving.
It's always said gently almost like a pet name for their naughty side.
I never thought anything of it and it's always light hearted never shouted or said harshly.
They are both toddlers and I've never seen it as a massively negative thing.
However today one DC was having a complete meltdown and tantrum as she was tired and hot and had been stopped doing something potentially dangerous and I cuddled her and asked her to stop being a little poop and she did calm down.
When I had succeeded in calming my DC and had let her go back to playing another mother that I hardly know came over and rather harshly informed that she had over heard me and started having a right go at me for being horrible to my children. Apparently calling my child this makes me a bad mum...?
So am I being unreasonable to call my child a little poop on the odd occasion or was this mother being overly harsh?
I'm not overly fussed either way just a bit curious.

Who the hell are these people who walk up to strangers and comment on things like this? Where do they come from? It honestly baffles me...

Yea it's nothing
I've said a lot worse

Why do you need to call them derogatory names? Can't you just not do that? You know what besom means in Scotland right and the roots of it?

Just don't call your kids anything derogatory. Really you can learn to talk to them without insulting them.

If I'm lifting her up I call her a hefty girl, chubba-chubbs or tell her she is of solid peasant stock

I hope you're kidding?

Does it upset them? I hated being called a poo as a child. Hated even more that adults wouldn't stop doing it when told it was upsetting.

How your children feel about it matters I think.

I’d have interpreted that as you calling your kid a wee shite in a twee sort of way.

It’d be a cold day in hell before I barged over and Aunt Lydia’d you on it though. 🙄

Why do you need to call them derogatory names?

For us 'burger' just developed from DP calling me it as a joke one day and then it became a thing, DD calls me a burger a lot, and her dad too, so we all do it. She knows it's not "nasty" as when we do all call each other these names we do all the fake dramatics and "oh how dare you call me that " and DD laughs etc. So if I do call her that when she's stroppy it's only to try and get her to laugh.

Bluntness - she is only six months old so I am fairly certain there is no lasting damage.

Why get in the habit though?
