We're in your opposite situation: we hire for about 6 hours a week for the two days a week I don't telework, but for late ES/ tween kids (but have been doing this for years). College kids are good for this, and we've found good people who stay with us for a year or two, but not forever. There are a lot of NOVA/ GMU, etc students who would love to earn $15-$20/ hour. We use care.com and sittercity, which does involve a lot of screening. The keys: be upfront about the number of hours; pay above market rate ($15-20 for a college student) because they will still have commenting time even if they don't work a full day; guarantee a minimum number of hours per week (which may mean you pay them not to work on snow days and holidays); do a test run (pay the for it!!) to make sure you are comfortable with the interactions; check references carefully; and particularly for an infant/ toddler, make sure they have experience with that age group. You won't get a professional nanny experience, but you should get someone who can care for and play with your child a few hours a week.
