I never got used to having a nanny, and even though it's made our lives more difficult in many ways not having her, my mental health is much better for it. I think I could have made things easier if I'd sat her down and said "the way you are putting the kids' toys away is driving me completely bugfuck, here is my system please use it" but honestly the whole relationship made me uncomfortable. I just didn't like someone else living in my house.
(The irony is, we may wind up with a babysitter again next year if Dylan gets into the school we want, because there will be 3 or 4 kids from this building all riding the bus together, and it makes much more sense to hire someone to pick them up at the bus stop and sit for a few hours every day than the sign them all up for afterschool care and work out the logistics of carpooling from Crown Heights at 5pm every day. BUT it will be a share, so not in our apartment all the time, and it will only be for 2-3 hours a day. How we work out on-the-books payment with 3 families involved, I have no idea. Maybe we'll just pay cash under the table and skip the tax break in favor of simplicity.)
