Babysitter Needed for my Children - Now Hiring

Seeking a babysitter near Cambridge for 2 boys, age 7 and 10. Ideally, we're hoping to find someone who can come to our house around 12:30, do light housekeeping, then meet the kids at school. The 10-year-old is pretty independent. The 7-year-old will need to be taken to an activity on Monday. Otherwise, when the weather is good, he plays at the park with his friends for as long as possible. The exact days are flexible; we're looking for two days/week.
