You don't just take a punt on a childcare provider like you might with temporary accommodation on AirBnB.

From personal experience and those of other parents I know, it's a heavily researched, quite intensive process involving multiple visits to different providers.

An AirBnB for long-term childcare seems like a non-starter, perhaps beyond initial discovery and shallow research.

Also, there are so many societal benefits to affordable child care for all. For example, more primary care givers returning to work, earning and therefore paying taxes etc.
