You realize a “babysitter who does full time care” is a nanny right? Again. The comparison is one on one care market rates vs daycare providers where there’s multiple kids to one adult. ETA: babysitters and Nannie’s can be used interchangeably in what is being discussed. Their home, the kids home. Whatever. It’s one on one specialized care vs a daycare center and the rates are very different as is the level of care and ease for parents. If a mom wants childcare at a more reasonable rate, it’s called go to a daycare center. Childcare is wildly expensive overall. But these two things are very different.
