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

We have a very smart, fun, creative 3-year-old who loves to play and a 2-month-old infant. We are looking for a nanny to help engage and give attention to our older girl and/or help care for our new family member to help out Dad when he is home alone with them. Approximately 3-4 days a week depending on our work schedules, 4-6 hours a day. We would prefer a nanny who is comfortable with pets and who is CPR certified.
