Families hire Night Nannies to come into the home for a few weeks or months after a baby is born to help the parents get some sleep!  A Night Nanny is a newborn specialist who typically works overnight, though some may come early to help with the early evening hours, or stay later in the morning. They either exclusively attend to the baby during the overnight hours, or will get up to help the mother if she wishes to breastfeed during the night (then burping, changing and soothing the infant so that the mother can return to sleep).  You may hire a Night Nanny for 7 nights a week or just a few.  A Night Nanny is especially helpful for families with multiples, or with older children who need to be cared for during the day as well.  They also tend to be experts in areas such as scheduling infants, feeding (lactation issues, effective bottle use/types), and other infant care areas and can provide suggestions to the parents on these topics if needed. 

In essence, the Night Nanny helps the family get through the initial few weeks or months of sleepless nights by caring for the baby during those challenging hours and letting the family sleep!
