Puppytooth Are you always this angry?
As indicated by the sad face I put at the end of my comment, which you seem to have ignored, it wasn't sarcasm, it was genuine sadness.
You said: There is so much I could say about safeguarding issues here but they’re bloody obvious - irrelevant if the Mum did it with good intentions, she does however need safeguarding training!
It was the rampant "obvious" comment, which you presume but isn't necessarily true. It's the irrelevant if the Mum did it with good intentions, when of course it's relevant, it's fundamental, this is a friend of the OP's and who she entrusts her daughter with. It's the arrogance and demanding tone of "she needs safeguarding training".
No she doesn't. She's a friend of the OP, she was looking after her daughter, she cared for her daughter. How incredibly OTT, arrogant - and angry - of you to state she needs safeguarding training, on which I presume you think she'll be told she not allowed to do what she did. Ridiculous.
