Hi, I’m Summer! I’m a preschool teacher and artist who absolutely loves working with kids. I’ve been caring for little ones since I was 15, from tiny babies to big kids, and I’m CPR, First Aid, and TrustLine certified. When I’m not in the classroom, I bring the fun to birthday parties as a face painter and balloon artist — so you can count on me to keep kids entertained with creativity, play, and lots of laughs. I love painting, singing, dancing, and exploring nature, and I enjoy sharing that joy with the children I care for.
“After Sky left my son lovingly said about 10 minutes later I wonder how she is doing...that shows you how much fun they had. ”
Hi families! My name is Amber, and I’m a nurturing and energetic caregiver with a strong background in both childcare and healthcare. I’m currently a nursing student at the University of San Francisco, where I’m deepening my knowledge of child development, safety, and wellness—skills I bring into every babysitting experience. With over 6 years of experience in customer-facing roles and a background supervising children ages 5 months to 6 years old at The Bar Method, I’ve developed the ability to stay calm under pressure, adapt quickly, and create fun, engaging, and safe environments for kids of all ages. What sets me apart: CPR/First Aid knowledge through my nursing education (and working toward official certification) Experience with Autism, ADHD, and Dementia A warm, friendly, and creative personality Experience tutoring peers, which translates into helping with homework or schoolwork at home A reliable, organized, and equity-driven mindset: I value every child’s uniqueness and treat them with respect and kindness. Whether you’re looking for a dependable sitter for your child, a responsible helper for school-age children, or someone to step in last-minute with patience and care, I’d love to support your family’s needs when I’m not busy with school. Additionally, I offer household cleaning and pet services! Because of my school schedule, I’m looking for occasional care! Looking forward to connecting!
“Amber was very kind and patient with my 3 year old daughter. She was actively engaged in playing and even brought some of her own things for them to do together.”
Hi I’m Jhenae! I’m a college student available for one-time or part time work during July-August 2026! I absolutely love working with children! For the past 6 years, I have cared for infants, toddlers, and youth! From part-time babysitting positions, to working summer camps, and volunteer work with children! Families would describe me as caring, responsible, and very attentive. I always prioritize children’s needs while making sure they are having fun! (Away from the technology, of course!) In addition, I have a license and my own car! I am willing to safely drive your children upon request! I am also experienced in caring for pets so I’m willing to help in any way possible! Feel free to reach out to me with any questions!
“Jhenae was awesome! She was kind, punctual, and my little guy loved playing with her! Looking forward to booking her again!”
Hi families! I’m Diamond, a proud Bay Area native and someone who has always had a natural love for caring for children. While I currently work in the legal field, caring for children has remained a meaningful part of my life for over 15 years, and it’s something I genuinely look forward to doing in my evenings and weekends. My experience with children started at a young age as a babysitter and grew into working for daycares and becoming a personal nanny for several wonderful families while I was in college. Over the years, I’ve had the opportunity to care for children from newborns all the way through their teenage years, and I truly enjoy getting to know each child and learning what makes them feel comfortable, happy, and cared for. Since 2019, I’ve also had the privilege of serving as a Special Court Advocate (CASA) for abused and neglected foster youth in the San Francisco Bay Area. Being a CASA has strengthened my passion for advocating for children and has taught me the importance of patience, compassion, consistency, and creating a safe space where children feel heard and valued. One of my favorite things about childcare is watching children grow and being someone they can feel comfortable around. In fact, many of the children I’ve cared for over the years have become like family to me. I don’t take that trust lightly. I believe in treating every child the way I would want my own children to be treated—with kindness, patience, respect, and genuine care. I also understand that every family is different. I’m happy to follow the routines and guidelines that are important to you, whether that means sticking to a bedtime routine, limiting screen time, accommodating dietary restrictions or allergies, helping with homework, or simply making sure your little one has a fun and engaging evening. My goal is for parents to feel completely comfortable and confident when they leave their children in my care. You shouldn’t have to wonder if your children are safe, happy, or being well cared for; I want you to have peace of mind knowing they’re in good hands. I would love the opportunity to become a trusted part of your family’s support system and, most importantly, to make sure your little ones feel safe, seen, and cared for while you’re away. ❤️
