I think a huge part of the stench is probably her clothing. I would make it clear to her that she must wash her clothing after every time she wears them which is not customary for everyone.

Unfortunately the only way that you can get through to your Nanny is to be direct.

But find a way to also be kind about it.

Just simply let her know that you + your family value cleanliness and that while your Nanny may not be aware of it - - oftentimes she tends to leave behind a negative scent.
Stress that this can be a distraction around the home & that a focus on personal hygiene on her part will be greatly appreciated.

Let her know that this is super awkward to address w/her but that you felt like it needed addressing.

Tell her what a wonderful Nanny she has been to your daughter and how appreciative you are for all that she is doing for your family.

Good luck!

I have relocated to the Middle East. I have a live in nanny who I really like and does her job well. My daughter is also very attached to her. It was really difficult for me to address because I hate awkward moments but she does not use deodorant and the whole apartment smells of her including my daughter who she always picks up. I bought her deodorant and showed her how to use it. There has been no improvement. I’m also always reminding her that she can use the washing machine whenever she wants but she always insists her clothes are clean when they are not. I don’t want to lose a good nanny over this but the smell is unbearable. The second time I addressed it she cried in her room. I don’t wanna lose a good nanny over this but I feel embarrassed whenever we go out and we can’t eat meals cos of the smell. I think I made the mistake of buying a spray one, and this time I’ll get a roll on. Need some advice on how else I can address it. It’s really awkward for me to mention it a third time. I’ve also noticed the hand soap in her bathroom has barely been used
