Babysitter Needed for my Children - Full-time / Part-time

We are looking for a nanny for 3 days a week starting in March. My son was born premature and we need someone who is reliable and experienced. CPR certified required and ok with a dog (25 pound mini Bernedoodle) light housekeeping only for babies needs such as laundry. Must have own car. My husband and I work and I am in the office 3 days a week but I am done with work at 3:30. Ideal day would be activities, playtime, lunch, snacks and nap time.
