Absolutely this.
I have a few friends with very solvent daughters that have had relationships with men with children and I introduced them to the nanny with a fanny label that I read on MN.
None of them had heard about it, but I filled them in and they were so alert and on point when tiny red flags waved and they were so quick to say directly to their daughters that they hoped they wouldn't become a nanny with a fanny.
All young women were surprised by the term AND to hear their mothers use it and to be so informed about the potential pitfalls.
I have two daughters and would be appalled to see them so used so am personally invested!
When one friend had pressure put on her to take his 4 year old for the night as he wanted to go to a stag, and his EX was already away, she very firmly told him no, she wasn't his nanny with a fanny and his childcare was NOTHING to do with her.
His outrage was enough for her to see her future and she walked.
Women fall into dynamics when we don't know any better, but we catch on quickly!....once we do.
