Temporary Night Nanny For 4 Month Old

Our 4-month-old is not yet a good sleeper. He is very sweet and smiley, but has reflux and doesn't settle down well and I'm going back to work. We're looking for a temporary nighttime infant caretaker to take care of most of the nighttime wake ups, feeding and soothing until he learns to sleep a little better (likely a few months). I'll likely still wake up a few times each night to breastfeed/pump. We also have a 3-year-old, but he sleeps well much of the time and we would handle any overnight wake ups ourselves. 13-16 nights a month (for the days I'm working, which vary and include some weekends). Requirements: - Background check - OK with dogs - Non smoker - Current on vaccines (flu, tdap, covid) - Prior night nanny experience with infants under 6 months - 3 references, including families for whom you have worked as night nanny
