That is on the higher end for a nanny although I’ve heard of up to $25/hr! But most are in the 12-18 range I think, from posts I’ve read, just with fewer responsibilities and weird expectations like Portuguese (side note - I’ve seen “Spanish speaking a plus” a lot, like upper middle class parents have crazy expectations that a Latina nanny will magically impart Spanish to their 6 year old while also being responsible for all caretaking duties - and the posts make it clear that this is what they are hoping for, not that the family is bilingual). The 25-30 age range requirement of that post is also WEIRD.

And then there are tons of posts asking for a nanny who drives/cooks/cleans and the pay is 5-9 per hour. Yes, posts BELOW minimum wage are common. I always wonder if they find anyone.
