Could be dealt with with a mom staying home and both lowering their financial expectations to more modest levels. Like our parents and grandparents did.
Could be dealt with by staying close to family (both male and female) so that there are more people to do the work. Especially helpful if you want to have more than 2 or 3 kids. Another bonus is you can keep more money in the family.
The atomic family isn’t actually functional without a big assist from extended family and trying to do without extended family is the reason why everything went to hell in a handbasket.
Parents are divorced and grandparents were big believers in extended family, like everyone was for thousands of years before the post-war period.
