Night Nurse / Nanny For Newborn

We have a newborn baby girl (less than a week old) and are looking for an overnight caretaker (e. g. 10pm-7am) at least a few days per week to take load off the mom. Would also need these times used for housework like laundry, meal prep, etc. In early January, demands are likely to increase as the dad will go back to work, so ideally would have someone with flexibility to increase hours / come during the day a few days a week, etc. but not required. Expect services needed for at least a few months. Must be up-to-date on vaccinations and take standard newborn health precautions. We have a small Maltese dog, so should also be comfortable around him.
