Nanny Needed For My Children

We are seeking a babysitter with a flexible late afternoon schedule for our 3 children in Wayland. Due to travel schedules, there are typically 4-6 days per month where we'd seek afternoon babysitting for our kids (9, 7, 4). Would include picking kids up from local school (starting at shortly before 4PM) until 530-6 p.m. Roughly 2 hours per day about 5 days per month, but days will be sporadic and can vary month to month.
