Nanny Needed For 2 Children In Brookline - Full-time / Part-time

My husband and I are looking to find a nanny to stay with our children during the day while we are at work. We were very lucky to have an amazing nanny for the past year, who has to move on to pursue her teaching career. We would need someone five days per week from 7 a.m. until 3 p.m. We are looking for someone who can keep up with our very active 2-year-old and1-year-old daughters. Preferably someone with CPR/First Aid training, and who would be able to take the girls to play groups and activities locally. Very occasional (rare) date nights and weekend help may be a possibility too. We also have two small dogs who would need to be let out in our fenced yard during the day. Thanks!
