This is just my experience at maybe ten companies, but it was always paid, not using PTO. It was only if you wanted to use more than the allotted time you’d need to start using PTO. Childcare is a whole different level of insane expense that really should be subsidized. When I was too young to consider children, I worked at a call center that had an on site preschool, but that phased out pretty shortly after I started as a cost cutting measure. Nothing has gotten anything but more difficult when it comes to raising kids.
