Nanny Needed For 1 Child In Brooklyn

I'm looking for a sitter who can help with my 3. 5-year-old on any of the following nights, ideally recurring: Monday and Wednesday evenings and alternating Fridays/Saturdays (meaning every other week). To clarify, I'm very flexible and you only need to be able to help some of those evenings. From September 26th through October 2nd, I'm looking for someone available any of those evenings as my kid's mom is traveling for work (we co-parent). I'll be in the apartment to help, especially at first, so I'm really looking for more of an occasional/part-time nanny situation rather than a traditional sitter, though in the future there may be nights when I go out after he's asleep. Location is Clinton Hill, and there's one small cat who generally avoids the kid!
