Hello!
I am Sarah Marstein, RN, CPNP, CBS.
For more than 28 years, I have dedicated my career to caring for children and families. I spent 15 years in the NICU and over 9 years working in pediatric primary care.
Through The Wonder Year, I combine my passion for infant feeding, child development, and family support to help parents navigate the first year with confidence.
My goal is to provide compassionate, evidence-based guidance so families feel empowered to thrive during this remarkable season of life!
“Sarah is very caring and takes the time to listen to all of your concerns. She helped us with breastfeeding as well as sleep concerns.”
The first year with a new baby is filled with incredible moments, but it can also be overwhelming and, at times, isolating. My goal is to provide personalized support as you navigate infant feeding and the many transitions of early parenthood. Together, we will work toward your goals, address your concerns, and build the confidence you need to thrive during your baby's first year.
