I just found this very strange story online although I'm not sure that I believe it:
"I’ve heard from very reputable friends of mine in the Windsor area with royal links due to work in the Household, guards& other connections about something that perked my interest after hearing about it a while back, and the recent news made me remember it again - I assume you’ve heard the stories about Meghan being found wandering around the estate, the parks and Windsor itself during the night after Archie was born, and having to be picked up by police? Well it’s been strongly supported that Sophie & Edward were up numerous nights looking after Archie whilst Harry went looking for Meghan with their security and select police, as due to the fact that nannies were extremely hard to come by for the Sussexes due to the high turnover and known abuse. This happened a couple of times, and usually ended with Archie ending up being looked after by Sophie due to the tense environment & arguments at Frogmore Cottage between Harry and Meghan.
This is said to be a very strong reason for why Sophie especially can’t stand Meghan, as Sophie is very passionate about family & her children, and very nearly died with an ectopic pregnancy losing her child, and very nearly lost Louise & died a second time, then having to go through IVF to have James."
