I'm a medical assistant at a pediatric and OBGYN clinic, currently applying to PA school and looking to babysit on the side. Kids have always been my passion! I'm CPR/First Aid & EMT certified with 3–5 years of hands-on experience. Whether you need a reliable date night sitter or just an extra set of caring hands, I'd love to be part of your village :)
Hi! My name is Colette, and I'm currently a graduate student at Stanford. I am offering child care, pet care, and household services. I love being a babysitter and have been watching toddlers and kids since I was 16. My responsibilities have included transportation to and from school, supervised activities, cooking, and homework help. I'm an experienced tutor from elementary to high school with a specialization in writing and English. I'm passionate about helping children love learning and feel confident in their skills! I also work as a household assistant and can cook, clean, and run errands. I enjoy cooking and baking, and I am happy to aid in preparing meals or teaching cooking and baking skills.

Hi- my name is Jamie, originally from Los Angeles, CA. I grew up in a big and very family oriented environment. I began babysitting at the age of 15. I have babysat children ranging from the ages of 2months-15 years old. I am comfortable babysitting children of all ages. I have done a lot of volunteer work in schools,daycares, churches, and more which have all required me to interact with children. I am a very responsible, patient, hardworking, approachable, nice, funny, energetic, understanding, and loving person. When I babysit I enjoy playing sports outside, doing crafts, playing board games, reading, and much more. I always love helping kids with homework. On my free time I love to read, watch movies, and have a good time. Overall, I like to believe that I am an outgoing individual that loves to be around kids and has a lot of patience.
**Please note: I do not generally take care of sick children. Please let me know in advance if anyone in your family is sick, especially if they’re contagious, so I can decide whether or not to come. If I’m not told about your sick child until I arrive, I reserve the right to leave to protect myself and the other children in my care. Thank you for understanding** I’m currently working full time as a manager in tech and am only babysitting very occasionally to supplement my income. I was a nanny throughout college to a family with two children, including one with autism. I’ve been babysitting for years for children of a variety of ages. I am not currently available for any regularly scheduled, part time, or full time positions. Please don’t hesitate to reach out if you’d like to discuss further.
