Karina McCarthy - Night Nanny

About Karina

I work in homes and virtually as a Newborn Care Specialist and Postpartum Doula, dedicated to supporting families during the earliest and most transformative stage of parenthood. My work centers on evidence-based newborn care, sleep shaping/sleep conditioning, feeding support, and creating calm, sustainable routines that help both babies and parents thrive. I believe the postpartum period deserves thoughtful, knowledgeable guidance, and I approach each family with professionalism, discretion, and deep respect for their values. My goal is not only to care for newborns overnight, during the day, and 24/7, but also to empower parents with the confidence and education they need long after my time in their home has ended. I primarily work through the agency Well Supported Family, which provides experienced in-home newborn and postpartum support for families across the United States. Our team includes Newborn Care Specialists, Postpartum Doulas, RNs and LPNs who offer overnight newborn care, daytime postpartum support, and extended care for families adjusting to life with a new baby. Our work focuses on safe sleep practices, feeding support, and helping parents establish sustainable routines so the entire family can rest and recover during the early weeks at home. I cannot contact on this site, so please email info@wellsupportedfamily.com

Working with Karina during the first months was truly one of the best decisions we made as new parents. From the very first night, we felt calm knowing our baby was in capable, knowledgeable hands. She not only helped us establish a gentle and sustainable sleep routine but also took the time to explain the ‘why’ behind everything, which gave us so much confidence. Our home felt peaceful, our baby was thriving, and we were finally able to rest. We’re incredibly grateful for the professionalism, warmth, and steady guidance during such a vulnerable time!

Frequently asked questions

What does an overnight newborn care specialist do?

An overnight Newborn Care Specialist provides professional newborn care during nighttime hours so parents can rest and recover. Overnight care typically includes feeding support [breast milk, formula, or combination feeding], diaper changes, soothing, burping, tracking sleep and feeding patterns, and establishing healthy sleep foundations. A Newborn Care Specialist also monitors for common newborn concerns such as reflux, gas discomfort, feeding challenges, and safe sleep practices. The goal of overnight newborn care is to support the baby’s development while helping parents get uninterrupted sleep and confidence in their newborn routine.

What is a night nurse?

A “night nurse” is a common but antiquated term for a professional who provides overnight newborn care so parents can sleep. In most cases, a night nurse is actually a Newborn Care Specialist, not a registered nurse. Overnight newborn care includes feeding support, diaper changes, soothing, burping, tracking sleep and feeding patterns, and helping establish healthy newborn sleep routines. Families hire a night nurse to reduce exhaustion, support postpartum recovery, and receive expert guidance during the first weeks and months with a new baby.
