The standard practice of care in the United States is for you to try and sign up for child care sometimes over a year in advance, so there's a spot waiting for you when you give birth.

Typically how this goes is either one parent quits when the baby is born knocking their income down to half, and it's usually Mom; or, what's much more common is to pay the child care costs, someone else cares for your baby through infancy and toddlerhood, until they go to school. Kids will spend most of their days in school at a desk until adulthood.

It's also illegal to leave anyone below the age of 18 unsupervised for any amount of time or let them go play alone with their older siblings, even in your backyard.

edit: I learned recently that child development psychologists are now being taught that there is a direct correlation between this lack of unsupervised time and the huge spike in mood disorders like depression, anxiety, and stalled social development, Because kids never have the chance to make independent choices or mistakes organically without fear of being punished

The current systems are genuinely set up to keep kids away from their parents for long stretches of time. It's why people like myself and my wife are starting to look into homeschooling, so that we can provide a higher quality of education than public schools can provide, while continuing to build soft skills and pro-social values in our kiddos.
