> have a parent stay at home with the child

Assumes there are two parents in the household. For two-parent households, assumes it can cover its expenses from the labor of only one of them. This option also doesn't address the fact that taking an extended break from working often has a long-term effect on one's income and career; this could change if doing so was more normalized, particularly for men.

> Extended families can pitch in

Assumes parents have extended family, that its members live close enough to do the work of child care, assumes the extended family members (including grandparents) are not also working and therefore unavailable, assumes they are capable and willing to provide free child care.
