Nanny Needed - Full-time / Part-time

We have a 2-year-old and a 7-year-old. The 7-year-old will mostly be at school most of the day/days but it would entail being with the 2-year-old all day and putting him down for nap/feeding him throughout the day and then picking up our 7-year-old from school (with the 2-year-old) later in the afternoon and staying until me or my husband come home from work around 5 or 6 p.m. This would be part time. It would vary from 2 days a week to 3 days a week, every other week. It would be Monday/Tuesday/Friday one week and then the following week Wednesday/Thursday and back and forth between those 2 schedules weekly.
