She may have initially thought that it would be no problem, then started thinking about it more...especially in light of the fact that she had to go through this a couple of times with her past provider. She may feel bad about it, but honestly, if I were her and had the option of a nanny, i probably would go for it too. It seems like her kids have been in a lot of back-up care over the time they've been in daycare and she probably just realized she really didn't want to keep doing that...or perhaps the husband came up with the nanny solution.
