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

Our days will vary depending on our work week. We are both nurses and looking for additional help. Most of the time another parent will be home. We are looking for someone to just be an extra hand and help us with childcare, lighthouse work. Looking for part-time hours approximately 10 to 20 hours a week. We have three children one 4 1/2-year-old who will be in school during the week and then a 6-month-old and a 1-month-old.
