Single-income families (ie. 2 parents and a kid on 1 income) are becoming a rarity. Until that's reversed, universal childcare is an inevitably.
You're calling for a move that would cement a destructive system in place rather than actually addressing the problems that create the system.
My dad didn't make shyt and neither me nor my two sisters were ever in childcare. I voluntarily have chosen to work in a field where I ain't gonna earn shyt, and no way I'm ever putting my daughters in childcare. If you have steady income, avoid debts, and aren't on the very bottom of the wage earners, you can make it work.
The problems are this:
Incomes too low on the bottom end
shytty parental leave laws
Too much debt (need to reform student debt, medical costs, and predatory loans)
Too many people are taught they have to chase money no matter how much they make
Sending kids to be raised by someone other than their parents doesn't solve any of those problems at all. A living wage, universal healthcare, student loan reform, better parental leave laws, doing everything possible to eliminate debt, teaching our communities to prioritize family over cash, and the UBI would all address the BASIC issues that we need to address.
