Maili $27 per hour for 1 child
Booked by 1 family in Mercer Island, WA

Hi, parents! I recently moved to the Seattle area (Issaquah) from San Diego and am looking to connect with families who need a reliable, caring babysitter for date nights, evenings, or weekends. This is actually my first time using UrbanSitter! Back in San Diego, I found all of my babysitting jobs through word of mouth. Families I worked with would recommend me to their friends, and I was babysitting for entire friend groups and neighboring families. I'm excited to use this platform to build those same long-term relationships with families here in Washington. I work full-time during the day, so I'm available after 5:00 PM on weekdays and have much more flexibility on weekends. I'm based in Issaquah and am happy to travel up to about 15 miles for the right family. A little about me: ⭐ 6+ years of babysitting and nanny experience ⭐ Experience with children of all ages, especially newborns and toddlers ⭐ CPR certified ⭐ Reliable transportation with a clean driving record ⭐ Fluent in English and Portuguese ⭐ Experience with potty training, introducing solid foods, establishing healthy sleep routines, and Montessori-inspired play Outside of work, I'm a huge animal lover (proud dog mom!) who loves spending time outdoors. I also enjoy cooking, and I have a big interest in holistic health and living a healthy, active lifestyle. Reading books, dancing to music, and playing sports are some of my favorite activities to do with kids. I love encouraging curiosity through stories while keeping little ones active with outdoor play, games, and plenty of fun. I always respect each family's routines, parenting style, and instructions while making sure the kids feel safe, happy, and excited to spend time together. I'd love the opportunity to meet your family and become your go-to sitter whenever you need an extra set of helping hands!

Kylie $30 per hour for 1 child

Hi, I go by Elliot and I use they/them pronouns! I am a nanny who got their start at an early learning school as a lead toddler teacher. I wanted to be able to provide more one on one care and I have since switched to nannying and I am currently training to become a postpartum doula. I love to make arts and crafts with the little ones and I don’t do any screen time. Outside here is so beautiful and I try to spend as much time as possible, walks and just soaks in the great grey overcast skies are my favorite.

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.

"We were incredibly grateful that Maya was able to help us out with a last-minute childcare emergency. She matched our 9-year-old's energy with arts & crafts, some quiet reading, and a walk around the neighborhood. We'd have Maya back in a heartbeat!"
