Or you could have affordable public daycare / public pre-school that starts when the kids are born. Why does everyone expect the government to take care of their kids from 6 to 18 but not from 0 to 6 in the US ? It's pretty ridiculous.
There's patchwork public daycare from age 3+, but mainly only for poverty cases. Daycare costs less than a job though, so you don't really need free day care as long as minimum wage is high enough.
