If I actually had money to burn and didn't work I think I would probably employ a full time nanny. That wouldn't mean that I didn't spend loads of time with my children though.
Firstly, it would mean that there was continuity of care for the children, when they had childcare it would be with the same person. Plus it would give flexibility, I would always be able to go where I liked at short notice and there would always be someone available to look after the kids.
As this woman says it enables her to spend one on one time with each child, which sounds really nice.
It sounds like she's with the nanny and children a lot of the time but just lets the nanny pick up the grotty jobs like the ironing and cleaning car seats and cleaning the kitchen.
It doesn't say anywhere that she's dumping the kids and not spending time with them, just that she has a nanny there to help out.
That article is just designed to promote jealousy, I doubt she even sounded that smug, I know what the mail are like they will have edited it like that.
