Makena $18 per hour for 1 child

Hi families! My name is Makena, and I'm a 20-year-old student at the University of Kentucky originally from San Ramon, California and will be in San Ramon for the summer. I've always enjoyed working with kids and have experience babysitting, including caring for a 10-year-old boy over the summer, experience as a summer camp counselor, and helped as an assistant cheer coach for the summer at California high school. During my time babysitting, I helped with meals, transportation, activities, and making sure he had a fun and safe time. I'm also comfortable caring for pets and have experience with both cats and dogs. As a former Division I athlete and lifelong cheerleader, I'm energetic, patient, good under pressure, and love to stay active. I enjoy creating a safe, positive, and judgement free environment where they can feel comfortable and have fun. I have my own car and am happy to help with pick-ups, drop-offs, and other tasks as needed. My goal is to be someone both kids and parents can trust, and I would love the opportunity to get to know your family!

Weronika $30 per hour for 1 child

I’m an experienced nanny, babysitter, and pet sitter with a strong background in child development and a genuine passion for working with children. I have cared for children as young as 2 months old up to 14 years old, including families with multiple children. My favorite age group to work with is infants through preschoolers (0–5 years), as I love supporting their early learning, curiosity, and social-emotional growth. I strive to create a safe, nurturing, and engaging environment where children feel comfortable, supported, and happy. I’m dependable, patient, and attentive to each family’s unique needs and routines. In addition to childcare, I also provide pet sitting and house sitting services, with experience caring for both cats and dogs. I treat every home, child, and pet with the same level of care and responsibility as if they were my own.

$20 per hour for 1 child
Booked by 2 families in Castro Valley, CA

Hello! My name is Jia and I am a recent graduate from San Francisco State University. I have an extensive background working with children, mainly grades K-6th. I have worked at an afterschool/summer program for 6 years (2 years volunteer, 4 years paid), looking after around 50 kids at a time. My roles there included chaperoning on daily park trips and weekly field trips, taking care of lunch and cleanup operations, as well as tutoring on math and English. My top priority is to always ensure the children are safe, but also to add some fun into their day! I understand that every child has different needs, so I’m always adapting and learning as I go. I can assist with cooking/meal prepping, cleaning, and running any errands as well if necessary. I also speak Mandarin and Cantonese!

“Jia is wonderful! Our 9 month old baby boy adored her immediately. She was so attentive and in tune to his needs, managed his nap schedule - which was difficult because she was with him right after a big trip where his sleep schedule got thrown off. She also completed house projects without direction while he was napping - washed all of his bottles, toys from our trip, mashed his sweet potatoes, organized his clothes, etc. We are so thrilled we found Jia and can’t wait to work with her again. ”

Booked by 4 families in Castro Valley, CA

Hi! I’m a caring, patient, and energetic caregiver who genuinely loves working with kids. I have experience with children of all ages and personalities, and I always aim to create a safe, fun, and supportive environment where kids feel comfortable and included. I currently work at an after-school program, which has helped me build strong skills in staying organized, keeping kids engaged, and handling different situations calmly. I also volunteer on some Sundays at a children’s ministry at church, where I usually work with toddlers—so I’m very comfortable with younger kids as well! In my free time, I enjoy staying active and being outdoors, and I like bringing that same fun, positive energy when I’m with kids—whether that’s playing games, helping with homework, or just keeping them entertained and happy. I’m reliable, easygoing, and someone parents can trust to take great care of their kids while making sure they have a good time too!
