OP: I agree you should talk to her about it.

To not do so if its still bothering you would be crazy and sure to doom your working relationship. Give her a chance to allay your fears.

It doesn't mean she will do it to every family she is with. She may have been commiserating with a friend or any number of circumstances that might cause us to do/say one thing we instantly know we should not have. Life goes on.

OP it would be so wrong to fire your nanny just because of what you heard??

As long as you treat her fairly, she most likely will not ever say anything like that about you.

I am a nanny who had families from hell. And yes, I talk about them when I am conversing with my close friends.
I also have had families I love dearly. With those families I would NEVER say a negative word. EVER.

Choose your battles.

My nanny talks crap about the other family in our nanny share. It makes me very uncomfortable. I assume she talks smack about me to the other mom.

That's uncalled for. OP came home early to her own home and heard the nanny venting.
