Evening Parents Helper Needed For 2 Children

We are looking for some supplemental help 3 nights a week for dual working parents with demanding jobs. We have a 2-year-old and a 11-week-old (will be 4 months upon start of job). We have a full time nanny but need support in evenings with the following tasks: - Prepare dinner for children and sometimes family - Help with bedtime routine; will oftentimes have one parent present but will need to be comfortable doing both solo - Household straightening - Occasional preschool pickup for toddler Would be a perfect opportunity for extra hours for a nanny that ends in the South End around 4 or 4:30. Open to different start times but need dinner on table by 6:15 p.m. Would like Tuesday, Wednesday, Thursday but if flexibility is available for some Mondays as well that would be a plus.
