Babysitter Needed for my Children - Now Hiring

We're looking for a reliable, experienced babysitter to care for our 1-year-old son for 4-5 hrs on an upcoming Sunday afternoon at our home in Arlington (Pentagon City/Crystal City area). Responsibilities include playing with him, feeding him a snack or meal, changing diapers, and potentially putting him down for/getting him up from a nap. We're looking for someone who has experience caring for babies and young toddlers, is attentive and comfortable following our usual routines, and has references. Infant/child CPR certification is a plus. This is a one-time position, though we'd be happy to find someone we could work with for occasional babysitting in the future.
