I really feel you on this, finding the right confinement nanny is so important especially for your first few weeks recovering. I don't have personal experience with PEM specifically, but a friend of mine used them and said the nanny was experienced, caring, and very hands-on with teaching her how to latch and care for the baby, which she really appreciated. For age, I think most mummies prefer someone with at least 10 to 15 years of experience rather than focusing on age alone, because experience really matters more leh. On sleep training from day 1, I would maybe check directly with PEM when you enquire, as it really depends on the individual nanny and their approach, so best to ask upfront during the matching process.
