We have a nanny, she is delightful and the children (3 and nearly 1) adore her. She's been with us since January and I have absolutely no hesitation leaving them with her...she babysits, but we've got into a situation where I dash home from work, put them to bed then dash out again. She's said she'd be very happy to do the bedtime routine, and I don't think the children would mind - in fact the oldest one would probably think it was a bit of a treat. So really, it's just me thinking that it's a big ask of someone (though they are pretty good at going to bed generally)/worrying the kids might freak out/feeling like a slack mother.
So, nannies - do you mind (really mind) being asked to do this? Parents - do you ask your nannies to do this?
