Hi families! I’m Fernanda a warm, reliable, and creative nanny based in Sausalito. I currently care for two wonderful girls (ages 7 and 9) and offer occasional babysitting for other families in the Bay Area. I have a background as a pediatric nutritionist, which helps me support children’s health, learning, and routines in a fun and balanced way. I’ve also worked as a youth leader, planning educational and recreational activities so I love keeping kids active, curious, and happy! Families describe me as patient, trustworthy, and full of positive energy. I always make sure children feel safe, loved, and have fun while their parents are away. I’m also comfortable driving, helping with homework, or caring for pets. If you’re looking for a dependable sitter who brings both care and creativity, I’d love to meet your family! 💛

Dear families, I love being around children, and started babysitting when I was in high school. I’m a warm and friendly person you can trust to take good care of your kid(s).

I am CPR/AED and First Aid certified. I’m a non smoker with a clean driving record who lives a very healthy lifestyle I am interested in building long lasting relationships with families. My childcare expertise also lies in raising my daughter to become a successful and independent adult, and I do understand the challenges and rewards that parents face. I’m a graduate of San Francisco State University, where I majored in Business Administration with an emphasis in Marketing. I’m also available to help with homework, household chores and pet care.

Hi. I grew up in Marin and just moved back after living in Boston for ten years. I have worked with children in many different capacities since high school. I have worked as a camp counselor, babysitter, and teacher in a non classroom setting. Most recently I worked at the Museum of Science in Boston as well as an attendant in the child care room in a gym. One of the hardest parts of moving back to California is leaving the families I had been babysitting for years. I am comfortable working with all age groups. I have worked with infants as young as nine days old to teens, though most of my work has been with children between three months and ten years. My experience has taught me that nothing is more exhilarating, rewarding, or exhausting then working with children. I have found that a good sense of humor and open communication with parents is essential. Having people trust me to look after their child/children is a great responsibility that I take seriously. A bit about me. I am an avid reader. Like many people, I love to travel. I am currently on a quest to visit as many national parks as I can - 54 thus far. I am always happiest when I can get outside though I must stay vigilant about not getting burned. I am a vegetarian who loves to bake with varying levels of success. I look forward to meeting and learning more about you.

“Rachel is so wonderful! Will love to book her again soon. ”
