A long time ago I used to do agency work in London, the agency I worked for supplied wealthy people, usually elderly, needing a nurse in the home for a while. I once went to a family where the parents had gone to Rio de Janeiro for six weeks, leaving the nine month old baby with the nanny. Nanny had slipped a disc and I had to care for baby and nanny.
Dad was a banker, the house was on a side street just off the King's Road. It had a below ground level large kitchen and dining room, slightly above ground floor was a large sitting room and a study, the next floor was a large room for the baby and a tiny room for the nanny, and the parents had their suite above (which I never ventured up to and didn't see). (Obviously there were loos/bathrooms as well).
The baby was weaned obviously, nanny had set up a kettle and area to mix up baby food in the room - I never gave him so much as a mashed banana 🤷♀️ but had to get a few bits from the kitchen.
When they were due home nanny said to me "Have you got all the baby food out of the kitchen? - father doesn't like to know there's a baby in the house"!!!
When they arrived I was sat at the far side of the large room feeding the baby. Father stuck his head around the door and said "Hello Tiger" before disappearing upstairs. Then Mother came in, picked up the baby and kissed him saying "Ooh you're delicious". Then she said to me "Do you mind if I go upstairs? I've got such jet lag and (father) has terrible diarrhoea". Then she disappeared upstairs and that's the last I saw of them.
I think it's fair to say the nanny employing classes are much more comfortable with leaving their children for extended periods. Nanny hadn't had a day off for eight weeks.
It's interesting that both William and Harry had a similar childhood, but William has been determined to prioritise family life and hands on parenting for which I much admire him. Harry doesn't seem to have absorbed the message so much.
(Just to say, I don't admire William's parenting on the basis of being a hands on father, but for him choosing a different style of parenting and not being deflected from that goal by protocol etc)
