Jenna is an experienced childcare provider and the Program Coordinator for Kinspace. With over 7 years of nannying and serving as an Au Pair in Amsterdam, the excitement of working with families never gets old for Jenna.

While abroad, Jenna learned different approaches and techniques from the host families and professional mentors. This invaluable experience has helped her understand family dynamics and all their nuances with a worldly perspective. Jenna is an organizational wizard who ensures that the classes run smoothly, and she brings her enthusiasm for helping new parents prepare for this next incredible chapter of their lives.

Callie Stemerman

Mama + Babe Group Lead Instructor

Callie has worked with children and families for more than 15 years. She has a Masters Degree in Early Childhood Education from Hunter College in New York City and has worked in varied educational settings, from intimate preschools to a large corporate early education center at Google.

After her first daughter was born, she hit the pause button on her teaching career to become a certified infant/toddler sleep consultant and hasn’t looked back. She feels it is very important to validate parents' feelings while working with them to develop a plan that will be successful for their individuated circumstance.

Callie is passionate about supporting and guiding new families based on their specific needs, beliefs, parenting style, as well as their children's unique temperament, developmental phase and age. She has taught Mommy and Me classes at Day One Baby and also has her own practice, Sleepless in SF, with the aim of working with Bay Area families in need of sleep guidance and support. She’s proud to work with families and provide them with unwavering support and education.
