Health & Safety Note: Because I often care for 2–3 different families in a single day, I do my best to keep everyone healthy and safe. For this reason, I’m not able to provide care for sick children or in homes where someone is currently unwell (cold, flu, fever, cough, etc.). If I arrive and notice signs of illness that I wasn’t informed about in advance, I may need to step away from the booking to avoid the risk of spreading anything to other children and families. Thank you so much for your understanding and support in keeping everyone well! ❤️ I’m a caring and experienced nanny with over 15 years of working with children of all ages — from tiny newborns to busy school-aged kids. I’ve worn many hats over the years: babysitter, summer camp group leader, and even some families trusted to help interview and choose the right nanny. I truly love what I do and always aim to create a warm, safe, and loving space where children can feel secure and thrive. Supporting parents and becoming a trusted part of the family is the heart of my work.

Hi! My name is Haley and I graduated from Stanford in 2024 with a B.S. in Product Design and was a D1 athlete on the field hockey team.

Hi! My name is Catia — I’m 25 years old and based in Palo Alto. I have several years of experience working with children from infants and toddlers through elementary school, both in private homes and educational settings. I currently work as an Infant & Toddler Teacher Assistant at a children’s center, where I help provide a safe, nurturing, and engaging environment for young children. Alongside my childcare experience, I’ve worked as a nanny and babysitter for multiple families, caring for children as young as 4 months through elementary school. I love creating fun, engaging, and safe environments where kids can learn, play, and feel comfortable being themselves. I’m also CPR and First Aid certified, bilingual in Spanish, and experienced in supporting children with different learning and behavioral needs. Families describe me as responsible, kind, and dependable, and I truly enjoy building positive relationships with both kids and parents. I’d love the opportunity to bring that same care and energy to your family! -Catia :)
Hi! My name is Liana and I’m looking for one-time and occasional babysitting jobs.

I have past experience as an Emergency Medical Technician (EMT), pediatric medical assistant, daycare volunteer, and math/reading tutor.

"UrbanSitter is my go-to for quality sitters! I can book weeks ahead of time or easily find a same-day sitter when in a bind. I even hired a part-time nanny during a daycare transition. Customer service is helpful and babysitters respond in a timely manner."
