Booked by 7 families in San Mateo, CA

Hello parents, I'm Carol and I'm 28 years old. I've been a nanny over 3 years here in the Bay Area with mostly experience with infants and toddlers. Depending on the kid's age I enjoy doing different activities indoors like reading books, doing arts and crafts, painting, etc and outdoors (always following the COVID guidelines). Exploring nature help kids to be away from electronics and let them discover new skills in them selves. I see myself as a punctual, patient, reliable and easygoing person, who is a good listener and follows parent's guidelines.

“We love having Carol watch our son (toddler). When we tell him in the morning that Carol is coming that evening he asks us through the day if she's here yet... and when we say no, he goes "Aww, man" (and squeals in delight when she arrives!). Carol is EXTREMELY attentive to Tristan, very sweet and caring with him. She gets down on his level, asks him questions about what he wants to do and makes sure he has a fun time. She does a "yes, and" when playing with him, and plays how he wants to play (of course keeping him safe). He loves it! And keeps the TV off, which is great. And her positive, infectious energy has us all smiling and laughing. As parents, we appreciate that she is responsible, communicates well, punctual, gets him fed, gets him to bed on time, and even does bath time when needed! We really look forward to being able to go out for dinner while having complete peace of mind. In short, we would highly recommend Carol to any friends of ours who are looking for a babysitter!”

Hi families! My name is Darby, and I’m a caring, experienced early childhood educator based in the Bay Area. I hold a B.A. in Child and Adolescent Development from San Francisco State University, with a minor in Special Education, and have worked with children for over 10 years as both a preschool teacher and nanny. Most of my experience is with children ages 1–5, though I also have about three years of experience caring for infants as young as 6 months old. I’m passionate about creating safe, nurturing, and engaging environments where children can learn, grow, and thrive. I take a play-based approach to caregiving and enjoy incorporating creativity, outdoor exploration, and age-appropriate learning into each day. I look forward to partnering with families to provide dependable, personalized care that meets each child’s unique needs.

Booked by 8 families in San Mateo, CA

Hello, I'm Jessica, a 34-year-old Brazilian currently studying Respiratory Care. My passion for caring for children began at the age of 16, looking after my cousins. I have extensive experience with infants and toddlers, although I adore children of all ages! On sunny days, I enjoy trips to the park or leisurely walks, and on rainy days, we can engage in creative activities like coloring, painting, or fort building. Outside of childcare, I relish hiking, exploring new destinations, and cherishing moments with friends. I also come with excellent references attesting to my dedication and competence in childcare.
