Night Nanny Needed For Newborn In Portland

Hello! I am looking for a night nanny (bottle feedings only) for our newborn daughter in Portland, Oregon for 2-3 nights a week for about 12 weeks. The hours would be approximately 9/10 p.m. to 6/7 a.m. (the website won't let me select an overnight range to display below), but I'm flexible and open to making that longer if you have a minimum requirement for night shifts! Looking for someone who could help out with light housekeeping tasks while not actively caring for baby during the night. We would also love to do some shorter daytime shifts, if possible (2 to 4 hours), especially in the first couple of weeks.
