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.
Did you have a nanny in 2017? You don’t mention it but from the amount of childcare, I would guess yes.
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.
