My stepmum brought up 3 kids whilst building up her own company. My brothers went to their grandparents and nursery. They're all fine.
A lot of families don't have the luxury of non-working, local grandparents who want to look after their DGCs. We don't.
'It takes a village' and all that.
One of the problems here is that traditional support networks have been eroded but not replaced with anything except private childcare. Women are now expected, if not required, to contribute financially to running a home and family - quite different from 100 years ago (in certain classes). But we haven't changed the way the world of work operates, we haven't added copious childcare alternatives (say, each place of work must have a creche attached by law or similar), our collective attitudes to BFing working mums are still ridiculous and so on and so forth.
You get, what, 20-30 hours free childcare from age 2-3? And 4-6 months paid ML (I'm self-employed so I don't know)? So from age 6mo - 2, you have zero financial support from anyone but your partner, should you have one.
The rug's been pulled out from under women's feet and not replaced with anything. Women now have the right to earn but also the responsibility and are still doing the vast majority of the homecare they did decades ago. And then some bugger comes along and says we're all terrible mums for putting our kids in childcare so we can tackle all this work? Get out of town.
