Seeking Occasional Night Nurse For Infant (and Later A FT Nanny)

We would like an occasional night nurse for our newborn in Boston. Baby is due Dec 17, so ideally someone with extensive infant experience who is comfortable with overnights (ideally we would do 7 p.m. to 7 a.m. a couple of times a week). Some light tidying up would be part of our caregiver's responsibilities. We have a large friendly (and hypoallergenic) doodle, so the person must be comfortable around dogs. No actual dog care is required for the night nurse position, just being okay with the dog being around.
