Booked by 1 family in San Mateo, CA

Hi! My name is Antonia. I have 10 years of nanny experience and recently graduated with a Bachelor’s degree in Nursing. I also have experience caring for elderly adults, which has helped me develop a compassionate, patient, and attentive approach to caregiving. I’ve volunteered in a preschool Spanish immersion classroom where I helped children with activities such as science, writing, and reading. I also volunteered for three years at at a Children’s Hospital assisting with newborn hearing screening program. I enjoy cooking, reading, and spending time outdoors. I’m very attentive, caring, and detail-oriented, which helps me provide thoughtful and safe care.

“Antonia was awesome with my 11 year old. She also handled my dog well who’s not used to strangers in the house. She’s like a big sister/cool aunt and my kid enjoyed hanging out with her a lot. Looking forward to more date nights with my wife knowing that Antonia is such a great fit for our family!”

Kailey $25 per hour for 1 child

Hi! I’m Kailey, I’ve always loved being around kids and helping families. I’m a reliable, patient, and attentive caregiver with hands-on experience caring for young children, including providing consistent care for a two-year-old for a family over an extended period of time. Through that experience, I became comfortable managing toddler routines such as meal prep, playtime, naps, diaper changes, and maintaining a safe and structured environment. I’ve grown up around children my whole life and naturally connect well with them. I genuinely enjoy being part of their learning and development — whether that’s encouraging creativity through play, reading together, helping with early learning skills, or simply being a calm and steady presence they can feel comfortable around. I understand how important trust is when inviting someone into your home and around your child. I prioritize safety, clear communication, and consistency, and I aim to support parents by making their day easier while ensuring their child feels secure and cared for. I’m dependable, organized, and attentive to individual needs, and I take pride in being someone families can rely on.

$40 per hour for 1 child
Booked by 1 family in San Mateo, CA

Hi there! I’m CPR certified and an LVN. I’ve cared for children ages 1-7 and am comfortable with diapers, toileting, and daily routines. I love helping families, keeping things organized, and creating a positive, caring environment. I drive my own car and am happy to help around the house with laundry (which I actually enjoy!), dishes, cleaning, and organizing. I’m also comfortable preparing simple breakfasts, lunches, dinners, and snacks. References are available!

“Cindy has been working with us for several months. She is a great communicator, calm, and knowledgeable. Cindy has managed to win over our baby, who has serious separation anxiety. She is awesome with our very outgoing preschooler. She is great at taking initiative and helping around the house. We are so lucky to have had her in our lives and would recommend her without hesitation. If she wasn’t moving, we would have loved to have kept working with her. Thank you, Cindy! ”

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

Hi Families! I’m a caring, dependable, and experienced caregiver with 20+ years of childcare experience. In addition to working with children over the years, I’m also a mother and grandmother, which has given me a strong understanding of children’s needs, routines, and the importance of creating a safe, loving environment. I’m patient, responsible, and genuinely enjoy caring for children of all ages. I can help with daily routines such as meals and snacks, playtime, supervision, and creating a calm, comfortable space for kids to feel happy and cared for. I also have a clean driving record, which makes me a reliable option for families who may need transportation help. I am a native Spanish speaker and also speak conversational English, so I’m happy to support bilingual families as well. Families can count on me to be trustworthy, attentive, clean, and nurturing, and I always strive to provide dependable care that gives parents peace of mind.

“Dalia was an excellent sitter and clearly has a lot of experience. She brought a whole bag of different hands-on activities and crafts, and quickly put our 3yo at ease. He was getting upset because he knew we were about to leave, but she had him so engaged that he didn’t mind at all when we said goodbye. I highly recommend her for your next booking!”

"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

"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)."
