What Is a Reasonable Raise for a Nanny Upon the Arrival of Another Child?

Basic Ranges

• For a live-in nanny, the arrival of another child should mean a raise between 10 and 15 percent, according to Great Care Nannies, a web-based nanny agency. The 2010 Nanny report by Park Slope Parents, a parenting organization for an upscale section of Brooklyn, New York, notes that a raise of one to two dollars per hour is average for most nannies after the arrival of a new child.

Factors for the Higher End of the Raise Range

• Certain mitigating factors may warrant giving your nanny a raise toward the higher end of the range described above. If your other children are with the nanny all day, and a new baby will literally double or triple her workload, her raise should be at the top of the range. This is especially important if your other children are still young enough to require constant and involved supervision. Caring for an infant and a 3 1/2-year-old eight hours a day is challenging, but caring for an infant and a 17-month-old, and possibly an additional toddler, is considerably more labor-intensive.

Lower Raise Range

• If your oldest two will be at school for eight of the 10 hours she works each day, you should still raise her salary, but you have more flexibility in the dollar amount than if she's caring for all three children the entire day. If your other children are old enough to get themselves in and out of a car and put their own shoes on, this, too, makes her increased workload easier to manage than if all your children are still in diapers and require frequent assistance.

Outside the Range

• Certain exceptions may mean giving your nanny a raise beyond the range listed above. If an older child has special needs or behavioral disorders, such as ADHD or autism -- even if she's in school part of the day -- the arrival of a new infant can make the workload much more taxing. The same is true if the newborn baby requires extra medical attention or has special needs.
