I've never had a nanny since I'm the last child of 5 but it made me remember something that I found quite funny
In one house we lived in back when I was around maybe 3 or 4 yo, there was a family's house close to us ... like from our kitchen we could see inside their living room kind of close
We got along nice with them, I think the two daughters of the family may have watch over me once or twice (can't really remember)
Anyway the point is that one day my mom was in the kitchen and when she look up, she saw me on the neighbours couch watching tv with the two daughters when I should be well inside of my own house. I apparently just knocked on their door and they let me in ... just to watch tv
Lets just say my mom was kind of flabbergasted
grandparents/family members etc do not count, of course. im talking someone that was paid to look after you
