Bee and I were just talking about this! I think I'd be fine with Charlie for a week (or indefinitely actually, although I'd have to learn how to make the soups and meals that Bee makes for him).
I would have a tough time doing a week with Olive on my own though. And if I had both the kids on my own, I think I would cry.
Could your SO survive for a week with an LO on their own?
