Also bear in mind that it’s not just the woman who can adjust her work hours.
it is equally as possible for him to go part time, ask for flexible hours etc in the same way you can. It’s not an obligate female role.
so instead of you taking all the risk, you could both work 3 or 4 days, meaning the child only needs one or two days childcare. Then it’s not impacting only you while he merrily accrues his pension and you taken all the child and home related crap as well as working.
this worked well for us. Dh went flexi- this was a big fight 20 years ago in a male dominated field, but he is incredibly proud that he contributed in some small way, as it’s now the norm in his company, and it’s also meant women employees have gone from almost zero to a significant %.
so he was able to do nursery runs, take time off for nativity and GP appointments, while I worked 3 long shifts a week and one on Saturday.
pensions are still roughly equal, he has a better relationship with the kids for being around, and he had to learn to cope with housework.
personally I prefer this- I tried being a sahm for a year after redundancy. It simply meant that was at work all the time, I was on my own with the kids, trying to keep on top of them, home, extra curriculars, all the odd jobs. Ime it’s much easier splitting, and also meant I kept my financial freedom and my pension, and I’ve had more of a life balance.
