Babysitter

We are looking for a great babysitter for 1 boy in Plano. Care is needed occasionally typically Thursday and/or Friday evenings from 8:00 p.m. to 12:00 a.m. (sometimes 1:00 AM), about twice a month. My son goes to bed around 8:00 PM, so this is mostly a low-key evening: getting him settled and being present in the home while he sleeps. We would prefer a babysitter who has their own car, who does not smoke, and who is CPR certified
