Night Time Sitter For Twin Newborn Babies

We are a nice family excited to be welcoming twin boys home in the near future! We are looking for help at night when our twin boys come home (late March 2024). We also have a 2 year old son (will be sleeping from 7 PM to 7 AM). We have a 6 year old Mini Aussie dog who is very energetic and nice! We are looking for a sitter with a calm presence who can help us for the first 1 month (possibly extending to 2 months) at night after the babies come home. Ideal hours are 5 PM to 7 or 8 AM.

The sitter will help us at night with the twin boys - changing diapers, comforting, & feeding bottles (babies will be primarily breastfed). Sitter will bring the babies to mom to feed at night. No household duties/laundry/cleaning will be expected - only caring for the twins overnight so mom can get rest between feedings.

We live in the Upper Eastside in Manhattan. Looking for help at night for 1-2 month, from approximately 5 PM to 7 AM, 5-7 nights per week. We can be flexible on time/days if necessary.
