I am a regular on this site but am posting under a different name today.
By way of background, we have had our nanny for nearly 5 years. She did after nursery pick up for us to begin with and then when my daughter started school and my nanny's main host family moved out of London she became full time for us.
She is very lovely, reliable etc. and my daughter adores her. But, I have an issue with the fact that her much older husband (his age is part of the thing that is creeping me out) who used to pick her up from work a couple of times a week now seems to be coming to spend some more time with them. I feel very uncomfortable about it but don't want to offend her by asking her not to have him interact with my daughter. My husband thinks that I should let it go, we trust her and should by default trust him. Any thoughts on how best to deal with this delicate situation would be very gratefully received.
