And you had 7*(3h+1.5h) for you plus 4*8h for the nanny = 63.5h in that week.
We didn’t have a nanny because our model was specialization, with stay-at-home-mom, which did and does work out well. Still, to be honest, our time budget was often in the negative when the kids were small.
In 2017 we had an au pair. See the “Ages 2y5m to 6y9m / 0y6m to 4y10m: au pairs” section of https://www.jefftk.com/p/childcare-iii for details.
I compared the time for childcare with our estimates, and things seem comparable:
42.5h (7 months) + 15.75h (5 years) + 9.25h (7 years) = 67.5h per week
And you had 7*(3h+1.5h) for you plus 4*8h for the nanny = 63.5h in that week.
