About Us

Happy Baby Signs  helps parents live with more joy by illuminating new ways to nurture, communicate, and connect with their children. We have been providing baby sign language classes since 2005 and have taught more than 20,000 parents how to sign with their babies. Our program is founded on more than four decades of evidence-based research and uses American Sign Language (ASL). We believe using ASL with the hearing population nourishes a more inclusive community. Our classes are a fun-filled way to teach parents how to introduce sign language into their baby's everyday routines through songs and interactive activities.

We offer on-demand recorded and live online classes. We have taught at multiple locations in the San Francisco Bay Area including Kaiser Permanente Hospitals, Sutter Health, Dignity Health, Stanford WorkLife, Children's Creative Learning Centers at Cisco Systems, Bright Horizons at Lucas Films Digital Arts, and multiple libraries and parent clubs.

Kathleen Harper is the author of The Well-Crafted Mom, co-author of Signs of a Happy Baby, a Certified Martha Beck Life Coach, and certified massage therapist (CMT) for moms.  She believes that at the heart of each of us, we know exactly what we need in order to be happy. As a life coach, Kathleen helps moms shift from overwhelm to awesome.  When Kathleen was a new mom she struggled with feeling confused, resentful, and overwhelmed. By focusing on the difficulties of motherhood, she missed out on so much joy.  "After working with my own life coach, my life doesn't look all that different - same house, same family, same job - but it FEELS extraordinary," she says. "I experience joy daily. I am authentic in my relationships. I truly love what is.  Life coaching changed my life.  Let it change yours."

Erika Vetter

Erika Vetter fell in love with sign language in her childhood, when she befriended a Deaf girl in her Brownie Scout troop. This friendship continued for many years and led her to volunteer in the hard-of-hearing preschool during recess when she was still in elementary school.  Erika received her Bachelor of Science in Speech Pathology and Audiology with Teacher Certification at Elmira College.  She earned her Master's Degree as a Teacher for the Deaf for grades K-12 from Canisius College in upstate New York.  Erika has taught both Deaf and hearing children for the past 18 years in schools such as the Pennsylvania School for the Deaf and the California School for the Deaf in Fremont and currently works as an ASL interpreter and instructor.  Erika's thesis on teaching ASL to preverbal hearing children, along with her recent coursework in bilingual education, has reinforced her belief that signing with children can produce amazing results.  All three of her children started signing between six and seven months old and still sign on a daily basis.  Erika delights in seeing ​children empowered with a tremendous ability to communicate effectively at a very early age and is eager to share her experience and enthusiasm with you.
