I would argue that the root problem here is: why isn't one parent able to stay home with the children? We shouldn't need nearly as many daycares as we currently do. It's simply a consequence of bad economic and social planning.
People could elect to do that. Overwhelmingly, they do not in the US, I think from a mix of many people find raising young kids tedious and that you would be out-bid for housing, goods, and services that you want by all the two-income families.
I love my kids dearly, but I'm not cut out to stay at home raising them full-time from age 0.25 through 5.
