Booked by 40 families in San Mateo, CA

I’m a reliable and trustworthy mom from Castro Valley with a wonderful ninth-grader. I previously taught at a public school here in Castro Valley, and I hold an active California teaching credential for multiple subjects and special education. I love caring for children, tutoring, and would be happy to support a parent who is homeschooling. I have a clean California driver’s license, full insurance coverage, and I’m certified to drive for field trips at my son’s school.

I was soooo lucky to work with Christine today! She was incredible with my kids and helped me with everything in my house Ive been trying to do for months, for hours on end. I am so grateful

Booked by 15 families in San Mateo, CA

My name is Rosey, and I have two years of experience working as an Au Pair, where I developed a strong passion for caring for children. My responsibilities included driving children to and from school and activities, preparing breakfast, lunch, and dinner, planning engaging daily activities, and assisting with bath time and bedtime routines. In addition to childcare, I have experience working as a household assistant. I am skilled in cooking, cleaning, and running household errands, and I take pride in keeping an organized and comfortable home environment. I am also comfortable providing care for seniors. I have firsthand experience caring for my grandparents, assisting them with daily activities and offering companionship and support.

Rosey is fantastic! Our little ones were completely captivated by her and even tried to follow her home. We look forward to having Rosey back again in the future (if we are lucky enough to find her available again).

Hi, my name is Wendy! 👋🏼 ☺️ I have an Associate’s Degree of Arts: Social and Behavioral Sciences and I recently got my Bachelor’s in Psychology. Im starting a Grad School Program fall 2026 for a LMFT at USF. My academic goal is to be a kids therapist because I truly love working with kids and that is the reason why I like babysitting since I get an opportunity to work with them. I am the eldest daughter of 4 siblings who are all boys and that I cared for since they were born until they grow up older. So the reason why I am very patient and kind with babies, toddlers and children of any ages is because I got the experience from taking care of my little brothers. But since 2020 I have been a nanny for 5 different families for about 1 or 2 years with each long term family. I can surely provide phone numbers for recommendation as well! One thing about me is that I love talking to babies even though they can’t answer back ha! I like taking toddlers and babies on walks, to closest library or just to explore any part of your place! I also enjoy teaching them the numbers, colors and singing appropriate age songs with them as well! I also love reading books with them. And lastly with children of 6-10+ years old I like to play table games or even painting as well. I am also a Spanish and English Tutor at Grade Potential Tutoring and Tutor Hero - so if you would like me to teach/practice with your children Spanish or English that’s something I am willing to work with them too :)

Wendy was so helpful to us at the last minute! She quickly bonded with my two year old and I felt very comfortable leaving the two of them to play all day together. My daughter even woke up the next day asking for her, which was really sweet to see. Wendy was punctual, kind, a responsive communicator and we can't wait to have her back!

Backup Babysitter on weekends only Hello Families, My name is Lia, and I’m a 31 year-old childcare professional living in San Jose with my husband, two hamsters and a Dalmatian dog. I used to work as full time nanny and then during the week as an early childhood afterschool instructor for the past 3 years but I transitioned back to child caregiving recently. I’m passionate about supporting children’s growth and development, with over 10 years of experience caring for kids of all ages, from infants to pre-teens. Why Families Choose Me: -Over 10 years of childcare experience, including newborns, infants, toddlers, and pre-teens. -5+ years of experience in the U.S., with a focus on nannying, teaching and occasional babysitting. -Master’s in Early Childhood Education. -First Aid, CPR and Mandate Reporter certified with annual update training. -Fluent in Portuguese and English, with conversational Spanish. -Comfortable with swimming pools, pets and providing light housekeeping (vacuuming, laundry, simple meal prep). -Experience with exceptional needs in both home and classroom settings. A Little More About Me: -Newborn Care Specialist certificate (but I rarely take care of newborns since I also work with school aged kids and need to be mindful of illnesses). -Fully vaccinated (COVID, flu, Tdap and others), boosted, and happy to wear a mask as needed. -I do not drive children, but am happy to assist with local activities and walking distance school pickups if needed. -I bring a nurturing, creative approach to caregiving and enjoy helping kids learn through play and exploration. I’d love the opportunity to support your family and help your children thrive. I look forward to connecting with you soon! Thank you for considering me. Best, Lia

"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
