Katy $30 per hour for 1 child

Hi! I’m Katy. I work full-time in HR and Operations during the week, so I’m mainly available for occasional evening and weekend babysitting. I graduated from UC Davis with bachelor’s degrees in Political Science and English and have been babysitting on weekends for over 10 years. During that time, I’ve had the opportunity to care for children of different ages. I also grew up with two younger siblings and worked in an after-school program at the Boys & Girls Club of the Peninsula, where I gained even more experience creating a fun, safe, and engaging environment for kids. I’ve always enjoyed being around children and getting to know their different personalities. I believe every child is different, so I try to get to know who they are and meet them where they’re at. Whether that means playing games, reading stories, doing crafts, or helping them get ready for bed, my goal is to help them feel safe, heard, comfortable, and have a good time while you’re away. I’d describe myself as patient, reliable, and easygoing. I know how important it is to find someone you trust with your kids, and I don’t take that responsibility lightly. I also like keeping parents updated while they’re out so they can enjoy their time knowing their kids are safe and doing well. If you’re looking for a dependable sitter for a date night, weekend plans, or just an occasional event, I’d be happy to help! I look forward to meeting you and your family.

Sophia $25 per hour for 1 child

Hi! I’m Sophia, a behavioral aide at a therapeutic day school who is passionate about supporting children’s growth, learning, and well-being. I’ve been babysitting and tutoring since I was 14 years old and have experience working with children of all ages, from newborns through teenagers. In addition to childcare, I have worked as a family assistant, helping with household tasks such as cooking, cleaning, running errands, and caring for pets. I enjoy being a dependable extra set of hands and helping families keep their busy lives running smoothly. In my current full-time role, I work with elementary and middle school students who have a variety of learning disabilities and mental health challenges. This experience has made me especially comfortable working with neurodivergent children and supporting kids in educational settings. My strengths include creating consistent routines, planning fun and engaging activities, helping with homework and academics, and building positive, supportive relationships with children. I’d love the opportunity to get to know your family and help create a safe, fun, and engaging environment for your children!
