Any form of child care that meets a child's developmental needs for attachment and attunement is okay, but it's parents who make these decisions. The state has no place in the child care decisions of the nation. That was the Liberal government's policy in 1999, and I hope they get back to it.
I've used mom care, dad care, grandmother care, uncle care, friend care, neighbour care, babysitter care--you name it. I lived underneath a day care for four and a half years, which was run by a close friend. I am entitled to a full fee subsidy. It would have been free, accessible, high quality, but I prefer my own care.
