Hello parents! My name is Sally, and I’m a mom of three. I used to be active on this platform a few years ago, and I’m excited to be back! I’m CPR certified and have been babysitting for over 10 years — everything from newborns to teenagers, including experience in a childcare center. Over the years, I’ve helped with school drop-offs and pick-ups, meal prep, park outings, and running errands. I have my own car, a valid driver’s license, and I’m a very safe and reliable driver. If you have any questions or would like to chat, feel free to send me a message. I’d love to get to know your family! Best, Sally

Booked by 1 family in San Mateo, CA

With over seven years of childcare experience in the United States, I am dedicated to providing a safe, nurturing, and engaging environment for children. In addition to my experience as a nanny, I worked as a teacher in Brazil, where I taught Portuguese as a second language in a multicultural school for children of diplomats. I also have a background as a Brazilian lawyer, which strengthened my organization, responsibility, and problem-solving skills. I am passionate about supporting children’s development, creating structured routines, and fostering a positive and caring environment. I would love the opportunity to contribute to your family.

Arrived on time, responsive and very professional. Kids like her too.

Booked by 9 families in San Mateo, CA

Hello, my name is Natalia. I am a patient, caring, and responsible childcare provider with several years of hands-on experience as a live-in nanny. I cared for an infant from 8 months old for two years, supporting daily routines such as feeding, naps, developmental play, and creating a safe, nurturing environment. I also worked as a live-in nanny for a family with two children (ages 6 and 10) for one year, where I assisted with school routines and daily activities. My responsibilities have included driving children to and from school and extracurricular activities, meal preparation, light housekeeping, laundry, and running errands such as grocery shopping, returns, and car washes. I am organized, proactive, and always focused on helping families maintain a smooth and structured routine. I truly enjoy spending time with children, engaging them in creative activities like arts and crafts, playing, and encouraging their curiosity and imagination. What I love most about children is their honesty and how they constantly surprise us with their unique perspectives. I am committed to providing a safe, supportive, and positive environment where children can feel happy and thrive

She was very good with my 1 year old son. She took him outside for a walk in the stroller. She played with him, engaged and connected with him. I heard giggles come out of baby and that's always a happy feeling. Showed up on time to work and stayed the full 8 hour assignment. I would hire her again.

Nurturing young minds and supporting families is my passion. For the past three years, I've had the joy of caring for children aged newborn to 11 years. I hold a graduate degree and find fulfillment in fostering each child's unique growth and development. My approach is patient, calm, creative, and friendly. I enjoy playing outdoor sports and educational games. I'm comfortable caring for up to three children and enforcing household rules. To keep you informed, I provide written daily reports, chat during pickup, and send regular text updates. I am also certified in CPR and First Aid. I speak English, Portuguese, and Spanish. I'm excited to bring my experience and dedication to your family, creating a safe and enriching environment where your children can thrive.

Appreciate the flexibility on short notice. She was very helpful!

"We absolutely LOVE Isa — our family was so fortunate to have found her through UrbanSitter. I'm a first-time mom, and it took me a long time to find a full-time nanny I could trust to care for our sweet infant boy. Our boy connected with her immediately, and we couldn't have asked for anyone else to care for him. Her calming presence was also perfect for parents like us who work from home. We feel so lucky UrbanSitter helped us find someone who has truly become a part of our family."

"I was so stressed about finding a part-time nanny for my 14-month-old son, who has moderate separation anxiety and hadn't been left with anyone but family before, but we were both immediately at ease in Buhay's presence. Her empathy and commitment to understanding child development are apparent in every interaction I've witnessed between her and my toddler. I feel very lucky to have found her."

"Erna watched our now 5 year old daughter and 3 year old son for a few years. She is punctual, responsible, honest, and playful. What we appreciated most was that she was thoughtful in ensuring that we had a little break; for example, when the kids were clingy, she was able to divert their attention with games or songs or walks to the park. We felt very comfortable leaving our kids with Erna because of her caring nature and experience that spans a decade (including being a live-in nanny)."

Eric D., dad of two
