Part-Time Afternoon Nanny Needed For 3 Children

We need afternoon help 4 days a week, anywhere from 2-3 weeks a month. Flexibility based on family work schedule is great but will plan monthly together. Primary responsibilities include school pick up for the two older kids (9 & 6), transportation to activities, homework support, snack and light meal prep, light housekeeping/basic cleanup, and evening pickup for toddler (2) from daycare. We're looking for a January 1st start date, ideally. We have a sweet dog who is very easy going and ideal candidate would be CPR trained.
