I read this article about virtual nannies on the BBC www.bbc.com/news/business-55058138 and found it interesting as my parents have been doing a similar thing with my 4yo DD after 3.30pm when she gets home from nursery. I'm obviously there WFH, but it just means she has someone to talk to, perform to, show her pictures to, talk through jigsaw puzzles, etc..
I wondered how many others are doing this and what yours get up to on facetime/zoom/Skype? It's cute to watch and means grandma and grandad still have a relationship, and they are also bored at home.
