That's correct. But IMO this entire thread is really missing the real issue, which is not so much the hiring of babysitters but our own family and friendship networks.
I wonder how many women here, who would never hire a male babysitter, would happily leave their kids with granddad, uncle, husband, step father etc. Relatively few I'd imagine.
Yet data already available shows how we're failing our children as the data is already telling us that it's people we know who have, and are continuing to abuse children. People outside of our networks make up a small number. Yet after 12 pages of to/fro about babysitters and risk, almost zilch about uncle John.
