As a babysitter/nanny, I also recommend Care.com instead of Sittercity. I can only recommend that one based on my experiences as a provider though, and not as a parent. But many of the families I've spoken with seem to prefer Care as well. Though they are both pretty similar, and either way definitely worth using. Having the background checks already done and on there waiting for you to see has got to eliminate some of the work and stress of hiring somebody. Plus I think a higher quaility of provider spends the $8 to have a profile on there verses someone who only posts for babysitting jobs on craigslist yk?
