Frances $23 per hour for 1 child

Hello! My name is Frances and I am a creative and fun-loving person who has a lot of experience working with children of all ages in various capacities. I started my childcare journey by helping to raise my little sister who is ten years younger than me and I've continued to grow as a childcare professional through adulthood. I've worked as a camp counselor at the Woodland Park Zoo where I was responsible for many children at once, I've volunteered as a creative writing teacher at an elementary school, and one of my greatest accomplishments is becoming a Certified Behavior Technician and working six months implementing and running treatment plans and therapeutic intervention designed by ABA therapists for children with autism of various ages (ages three to sixteen). I cook and clean, I'm CPR/First Aid certified, I love pets, and I have a safe car and a clean driving record. I am a molecular biology student at UW and I currently work part time as a Phlebotomist with the hopes of attending medical school in the future. I'd love to chat more about your needs and how I can best support your family!

Sofia $28 per hour for 1 child

I have always enjoyed working with children. After finishing my degree in Psychology in 2021, I had the opportunity to travel to Brazil to work with the United Nations on one of the 17 Sustainable Development Goals (Quality Education) for 2 months, where I taught Spanish and organized educational activities for children. My experience in childcare has been truly vocational and inspiring for me. I cared for a boy for six months, from 1. 5 years old until he turned 2. Then, I took care of a second child from 9 months until he was 2. 5 years old. Currently, I am taking care of a little girl since she was 4 months and she is now 2 years old! I enjoy helping children with their emotional growth and daily routines, while fostering a safe environment where they can explore and play.

Renn $25 per hour for 1 child

I am a (current) mental health therapist and experienced nanny looking for time-limited gigs (like vacations) or evening & weekend opportunities, including nannying/babysitting, house sitting, household management, travel nannying, pet sitting or other related tasks. I was a long-term nanny for families in the Seattle area from 2[removed] and 2018-2022. I also have experience with household management and organization/systems implementation to help households run smoothly, as well as ample experience with pet sitting. I have a 10 year old doodle myself who is the sweetest pup you’ll ever meet! I have also nannied for 3 kids for a week while their parents went on vacation, and we had a blast! I am a mental health therapist by day, with afternoons/evenings and weekends available. To be transparent, my long-distance partner and I are looking to relocate in the next year, and we want to save some extra funds to ease the move & extend time off together. I could add more therapy clients, however, I quite enjoy nannying (and other related jobs) and it would be a lovely change of pace. If you’re looking for a long-term person, I won’t be the best fit. But if you need someone to watch your pets on vacation, household organizing, weekend babysitting or vacation coverage, I am great at what I do and will provide a fun, safe, and interactive experience for anyone in my care.

Jennifer $33 per hour for 1 child

Hi families! My name is Jenn, and I’m an experienced, compassionate, and reliable caregiver with several years of experience working with children of different ages, backgrounds, and developmental needs. I have a Bachelor’s degree in Sociology from the University of Washington and am currently pursuing my Master’s in Marriage and Family Therapy at Pacific Lutheran University. My background includes working as a Registered Behavior Technician (RBT), supporting children with autism and developmental differences, teaching, and working in early childhood education and family services. These experiences have helped me develop patience, creativity, adaptability, and a strong understanding of children’s emotional, social, and behavioral development. I believe in creating a safe, nurturing, and engaging environment where children feel supported, understood, and encouraged to explore the world around them. I enjoy incorporating play, creativity, outdoor activities, and age-appropriate learning into my time with children. I’m currently looking for part-time or occasional babysitting opportunities that fit around my graduate school schedule. I would love the opportunity to connect with your family and provide dependable care for your little ones!
