Looking For Overnight Nanny Assistance With Newborn

Baby is newborn, and formula fed. We need assistance with watching our angel throughout the night (Shift would be 10pm-6am), feeding, soothing, burping, changing, etc. Days needed would ideally be Sunday, Tuesday, and Thursday but can be flexible on that, as long as it's 3 days a week minimum. Potential to move to 4 days. We would prefer a nanny who has their own car and who does not smoke.
