Flexible Hours - Nanny Needed - Now Hiring

Hello! I'm looking for a mother's helper for my son who is 6 months old. My mom cares for him during the day, but she has meetings at times and needs a few hours each day to focus on work or has to leave to go to the office. There will also be occasional days when we need full-day coverage but that would be planned far out. Ideally find if the day could be extended until 6 that would be ideal, but 5 or 530 would work. Start time is slightly flexible as well
