She 100% has a live in nanny, i'm even more certain of it now after this holiday. I reckon she gets paid a fuck load and will have signed an NDA of some sort. You never see their supposed family/friends on these little 'weekend escapes' and no way would they be leaving him with a stranger for the night. The nanny will have her own room in the house and travel with them on their holidays so they can go out and do things without their child, as you do
Also - WELL DESERVED DOWN TIME??! Are you joking?! Her ENTIRE life is downtime hahaha. She literally has the easiest life in the entire world.
