[Highland Park] Part-time Babysitter needed

I am looking for a babysitter to take on two afternoons per week, preferably Tuesdays and Thursdays from 1:00 to 5:00pm, starting immediately. Hours and days are somewhat flexible, as I work from home, but occasionally have appointments around the Pittsburgh area. My son is 11 months old and active, but well-behaved and very agreeable. We are also expecting a new baby in June, so experience with infants is a huge plus. Candidates must be dog-friendly and willing to take on occasional, light, baby-related tasks during nap times. Willingness to take baby and dog for walks will be regarded highly.
