I need a responsible babysitter for two children ages 8 and 5. The schedule starts as soon as possible and includes school pick up at PS 321 upper and lower schools on Seventh Avenue in Park Slope. The afternoon sitter will be responsible for taking them to any activities in the neighborhood or to the library or playground and bringing them home. Other responsibilities include giving them a snack and if time permits, helping mom out picking up their toys and putting their laundry in and out of the machines.
