Hi Bay Area families,🌉 I’m Zu, I’m a mom, a mother’s helper, and someone who genuinely loves taking care of kids and helping families.🤍 I’ve been caring for children for over 15 years and have had the opportunity to help more than 200 families through UrbanSitter, caring for everyone from newborns to teenagers. I was a Sunday school teacher for 8 years as well. I’m the kind of person who likes to jump in and help wherever I’m needed. Need someone to pick up the kids, run to the grocery store, help with potty training, change diapers, clean bottles, do laundry, fold and put clothes away, tidy up, or even make dinner? I’m happy to help. Being a parents is already hard, while juggling with work, life and family, let me help you! And if your kids just want someone to hang out and play with them, I’m there for that too! I love reading, playing, getting outside, doing activities, and just being present with kids. I’m not on my phone while I’m caring for them, and I’m happy to follow your family’s preferences when it comes to screen time and routines. I’m also a mom to a toddler, (my boy Santi), so I understand how much an extra set of reliable hands can mean! I have a clean driving record, I love organizing and helping manage a home, and most importantly, I really love kids. Oh, and I’m CPR certified! Whether you need a mother’s helper, house manager, part-time help, date-night care, or simply someone to come in and make your day a little easier, that’s exactly what I’m here for. You’ll find someone reliable, friendly, caring, and ready to help wherever you need me. ❤️ I live in San Carlos, and willing to drive up to 15 miles to help you.🤍

Hi, I’m Cristina! I have over six years of experience caring for children from 10 months to 14 years old. I love babysitting because I enjoy doing fun projects with kids and taking them to the park. My interest in childcare really grew from helping take care of my little cousin with Down syndrome, which taught me a lot about patience and how rewarding it is to care for children. A little about me: I love reading, spending time with family and friends, and learning new things. I also have a dog that I love taking to the beach! I’m open to traveling with families as well. Thanks so much for taking the time to read a little about me!

Hi - My name is Mariana and I’m looking for a 2 part time, weekdays, one in the morning one afternoon, open for a full time was well, and babysitting. Start in November I love working with kids and have experience caring for children from 6 months to 11 years old. I’m comfortable with everything from diaper changes to preparing meals, and I bring a mix of fun and learning to our time together — reading stories, coloring, puzzles, going to the park, and even the occasional dance party. I’m responsible, organized, and genuinely enjoy spending my days with kids. I’m CPR certified, a strong swimmer, fully vaccinated, and a safe driver.

“Mariana is an excellent babysitter. She is extremely professional and courteous. She’s experienced, confident, and communicated very well with our five year old daughter who is looking forward to playing with her again. She arrived a few minutes earlier and immediately dove in and engaged with our daughter. We are looking forward to having her babysit our daughter soon.”

Hello, My name is Opal. I live in Redwood City and currently work as a Family Assistant in the area. I’m looking to add more hours to my schedule—approximately 20 hours per week in March and around 30 hours per week starting in April. My schedule is flexible, and I am available to start the week of March 16th. Family Assistance (4 years of experience) I can help with meal prep (lunch and dinner), keeping the home organized and tidy, reorganizing children’s closets, sorting outgrown clothes for donation, and running household errands. I’m also happy to handle grocery shopping (Whole Foods pickup, Trader Joe’s, Costco), return packages, and take the family car for maintenance. I’m very organized and also enjoy cooking, especially Thai food. Pet Care I’m comfortable helping with pet care, including feeding, walking, taking pets to grooming or vet appointments, and picking up pet supplies. Childcare (11 years of experience) I have extensive childcare experience, including 5+ years caring for newborns, infants, and toddlers. I am Infant CPR and First Aid certified, fully vaccinated with boosters, and have received my flu shot and TDAP. I truly enjoy working with children and love engaging them through reading, singing, playing, and outdoor activities such as going to the park, library, and museums. I have my own car, a California driver’s license with a clean driving record, and can safely drive children using the family car. I’m a fun, punctual, reliable, patient, flexible, and positive person who loves both children and animals. I’m happy to provide references upon request. Rate: $38–$40 per hour. Thank you, and I look forward to hearing from you. Best regards, Opal

"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)."
