Booked by 4 families in Mill Valley, CA

I started nannying after leaving my job as a TV producer when my son was born in 2004. Since then I've cared for numerous newborns, babies, and toddlers, including several sets of twins. The last few years I've had the joy of nannying my niece's twin boys who just turned 4. As preemies, they required specialized round-the-clock care that I was privileged to be part of. Now they're healthy, happy, and enjoying preschool, so my time has freed up and I'd love to share it with other babies and little ones. Most recently I’ve cared for a new set of twin boys, in addition to two separate 4 month old girls. Because I’m not looking for full time work, my schedule is often flexible. One of my hobbies is photography, so you can expect plenty of photos of your little one throughout our time together.

“Bonita is so wonderful! She watched our daughter Olive starting from when she was just three months old—we were nervous to have someone besides us take care of her so young, but Bonita is so good with babies and made us feel comfortable immediately. She’s incredibly reliable, flexible, and just a really kind and warm person. Can’t recommend her enough!”

I have worked in the professional nanny industry for close to fifteen years. Before that, I worked as an occasional babysitter and camp counselor. I’m certified in first aid and infant/child/adult CPR. I have an undergraduate degree in interdisciplinary studies (social science concentration) from The Catholic University of America. As well as a graduate certificate in human services from Wilmington University. I’m a patient and empathetic person. I think children have a contagious sense of wonder and happiness. They truly make the world a better place. I’m currently looking for occasional babysitting jobs outside my regular nanny position. I look forward to hearing from you!

Hi there! I'm Brittany- a third generation San Francisco native and USF graduate with a degree in Sociology. Growing up in a big family, I know firsthand how busy life can get, and am always happy to jump in and lend a helping hand wherever I can :) I’ve been working with children for over a decade through childcare, tutoring, and volunteer work. I’m experienced with all ages (infants to preteens), and love engaging with kids through arts & crafts, music, outdoor play, and creative activities. In recent years, I stepped away from UrbanSitter to care for an aging relative, but am excited to connect with more wonderful families. My schedule is fairly flexible, so feel free to reach out- I’d love to hear from you!

“Brittany took care of our 2 year old daughter while we were out. She was prompt, friendly, and got along well with our daughter. She put her to bed with no problem. We would definitely hire Brittany again! ”
