Hi, I’m Leighanna! I’m a nursing student with over 11 years of babysitting experience, starting when I was just 13. I’ve cared for children of all ages and pride myself on being reliable, attentive, and calm in any situation. Alongside childcare, I also offer dog sitting—I have two sweet pups of my own, Okia and Yumi, so animals are very close to my heart. I earned my undergraduate degree from San Francisco State University and am now pursuing my master’s in Nursing. Outside of school and sitting, I love to bake and have been dancing for 22 years, which keeps me creative, active, and full of energy. I bring that same warmth, responsibility, and enthusiasm into every family I work with and truly enjoy creating a safe, fun, and supportive environment for kids. 🚗 Rates & Transportation: 🚗 My standard rate is $30/hour minimum for one child. I’m always happy to discuss rates and am comfortable accepting bookings at a different posted rate if one is listed. For families located across the bridge, I kindly ask for assistance with the bridge toll, which is currently $8.50. ❌Cancellations❌ Because I reserve time specifically for your family and may turn down other opportunities, any booking canceled with less than 48 hours’ notice will incur a cancellation fee equal to one hour of care at my normal rate. If plans change or a booking ends early for reasons outside of my control, I ask that the reserved booking time be honored for payment unless we’ve agreed on a different arrangement in advance. I completely understand that unexpected situations can come up, and I appreciate your understanding and consideration of my time. Thank you!

Hi! My name is Alondra, and I am currently a senior at the University of San Francisco majoring in Nursing. My goal is to become a Pediatric Nurse Practitioner, and I have a genuine passion for caring for children and supporting their growth and well-being. I offer reliable, compassionate childcare whenever my school schedule allows. I am CPR certified and a registered caregiver through the state, with experience caring for both children and my own grandparents. My healthcare background has taught me patience, responsibility, and how to remain calm in different situations, giving parents peace of mind while their children are in my care. I am fluent in both English and Spanish, so I am happy to communicate with bilingual families or help children practice Spanish. I’ve also been dancing since I was 3 years old and love incorporating fun, creative activities like dancing, crafts, reading, outdoor play, and games into my time with kids. I love dogs, so I’m more than comfortable caring for pets as well! My goal is to create a safe, engaging, and positive environment where children feel comfortable, supported, and have fun. I understand how important it is for parents to trust the person caring for their children, and I strive to be dependable, attentive, and communicative every step of the way. I look forward to meeting your family!
“Prompt, communicative and a hit with our baby boy! Hired before and would hire again!”
Dear Families: I AM LOOKING FOR A JOB DURING WEEK MORNINGS FROM 7:00 AM UNTIL AROUND 3:00 PM. There is some flexibility. My name is Maria Elena. I’m originally from El Salvador. I hold a valid California driver's license. I've lived in the Bay Area for 33 years. I earned an Associate Degree in Arts and completed 12 credit units in early childhood development. I have 20 years of experience working with children from infants to 10-year-olds. Activities: I truly enjoy spending time with children doing a variety of activities, from reading books to exploring places nearby, such as the library, the Zoo, museums, aquariums, and parks. I am also happy to care for the children's things and help with light organizing and cooking simple meals. I expect to work in a good environment and offer the best of myself to the children.
