While I am glad some people have found success on Craigslist, with me it has been the complete opposite.
The families in my area have been flaky & scatterbrained.
Since they didn't invest a penny toward finding a Nanny, I am guessing that it means they don't care if they change their minds later on.
Or maybe they are not sure if they even want to hire a Nanny, so they are just interviewing people to see what is out there.
Families that actually take the time and effort to invest in their Nanny search are usually more serious-minded about selecting a Nanny and are less flaky.
I prefer to find parents on childcare websites vs. CL.
