South San Francisco
$30 per hour for 1 child
Booked by 2 families in San Mateo, CA

Hi! My name is Janetzy, and I have over 7 years of experience working with children of all ages. I have 4+ years of experience caring for infants, 6+ years working with toddlers, and over 7 years supporting and mentoring children in general. My journey in childcare began in 2019 when I started working at an after-school program, where I tutored elementary school students, supervised activities, and helped create a safe and engaging environment for children after school. Through that experience, I discovered how much I genuinely enjoy working with kids and helping them learn, grow, and build confidence. Since then, I have continued to gain experience through babysitting and nannying, caring for children with a variety of needs, personalities, and age groups. In addition to my childcare experience, I have a creative background and earned my degree in Film and Television Production from USC. I currently pursue creative work as a filmmaker, director, and editor. My creative background allows me to bring imagination, storytelling, arts and crafts, and fun educational activities into my time with children. I love encouraging creativity, curiosity, and self-expression while making sure children feel supported and engaged. I am fluent in both English and Spanish, which allows me to communicate effectively with bilingual families and introduce children to a second language through everyday conversation, play, and learning activities when desired. I am patient, responsible, dependable, and passionate about creating a nurturing environment where children feel safe, valued, and cared for. Whether it's helping with homework, planning activities, maintaining routines, or simply being a positive role model, I strive to make a meaningful impact on the families I work with. I look forward to meeting your family!

Janetzy was our nanny full time taking care of my daughter since she was 4 months old. She was also taking care of my toddler in the evening and we could not have asked for a better caregiver. She is incredibly reliable, punctual, trustworthy, and wonderful with young children. She quickly became an important part of our family and we feel incredibly fortunate to have had her in our lives during those early year. I cannot recommend her enough. Marina

Isabella 1 review
Redwood City
$30 per hour for 1 child
Booked by 1 family in San Mateo, CA

My name is Isabella, I’m Brazilian, and I’m passionate about caring for both kids and pets. I’m responsible, patient, and creative, and I love creating a positive and fun environment for children. I have experience working with kids and currently help care for children at my church, which has strengthened my communication and nurturing skills. I also have experience with pet care and have a dog of my own, so I understand how important it is to keep pets loved, safe, and well cared for. I’m also preparing to start college to study psychology, as I genuinely enjoy understanding people and helping others. Families can count on me to be reliable, kind, and attentive to every detail that makes their home feel peaceful and cared for.

Isabella arrived on time to our booking. We booked her services to allow the mom to have time to recover from the day. Isabella held baby with care and she was patient with baby when it was time to feed baby. She asked questions to be able to do the tasks correctly and was a calm presence in the house. Our family recommends her services.

Jessica C 2 reviews
Redwood City
$30 per hour for 1 child

My name is Jessica, and I bring a strong blend of experience, education, and genuine care to every family I work with. With a background as an Au Pair in the U.S., professional Nanny, and two years as a Teacher Assistant in Brazil, I have cared for children from infancy to school age, creating safe, structured, and joyful environments where kids can thrive. I am CPR and First Aid certified and hold an RPC (Responsible Program Candidate) certificate from my pre-Au Pair training, which focused on child development, safety, and positive discipline. Additionally, I hold a technical degree in Nutrition (Brazil), which allows me to support healthy eating habits and prepare balanced meals for children if necessary. I will always prioritize the choices and preferences of the parents first. My approach combines warmth, responsibility, and creativity. I love organizing engaging activities—arts and crafts, outdoor play, reading, and routines—always adapted to the child’s age and interests. What I can provide for your family: • Loving, attentive care for infants, toddlers, and school-aged children • Support with routines: feeding, naps, diaper changes, and developmental milestones • Fun activities and homework assistance • Reliability, punctuality, and clear communication Families often describe me as caring, trustworthy, and proactive. I take pride in being a calm, positive presence for children, helping them feel safe and happy. If you want, I’d be happy to share my complete CV. Looking forward to meeting your family and providing exceptional care!

Jessica worked at our school in Brazil, where I am the director and owner, caring for children from 3 months to 6 years old. She spent the mornings assisting with the care of the children in the nursery and the afternoons as a teacher assistant in a classroom with 4- to 5-year-olds. She was professional, dedicated, punctual, extremely reliable, affectionate with the children, and maintained a happy, healthy, and safe environment for them. I highly recommend her!

Hi! I’m 28, work in the medical field, and have 13 years of babysitting experience. I’ve grown close with the families I’ve worked with and always aim to make kids feel safe, supported, and heard. I’m used to school pickups, driving to activities, helping with homework, and keeping routines on track. I’d be happy to chat and see if I’m the right fit for what your family needs. CPR certified

Victoria was amazing with my 3 year old. They played, went for a walk and Victoria had her bathed and in her PJs by the time I got home. Victoria is on it and has great engagement with children.

"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."

Kamilah W., mom of one

photo of quoted parent Eric

"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
