I love working with kids, and have more than 10 years experience working with kids from ages 1-16 both in an academic setting and as a nanny-like role.

Cole helped us out in a pinch when our son was home sick from daycare. The two of them had a great day together going to the park, reading books and drawing pictures. Would definitely hire again.

Kasteyl 1 review
$27 per hour for 1 child

I've been the neighborhood babysitter and a part time nanny most of my life. I have the most experience with toddlers through age six, but I've also worked with infants and tween twins. I'm down to earth, have years of experience, and strongly believe that it's our job to raise the best, kindest, and well rounded humans that we can. I have been with my current Nanny Family since Jan 2020 and have picked up the rare date night for friends and family. I am looking for more part time work starting in September, preferably 8-16 hours, 1-2 days a week. I have a car, am happy to do light housework, go on adventures with the kiddos, and help with homework after school. I'm energetic and outgoing, with a love of math, science, and the imagination. I am also enthusiastic about date night sitting, nanny fill ins, and more! I miss working with kids while mine are in school! I’m COVID vaxxed and conscious, I mask when I’m indoors in public spaces. If you are a COVID conscious family I’m happy to discuss my risk factors and test before caring for your kiddo(s).

Kas is an amazing babysitter. My daughter is nonverbal autistic and has mild cerebral palsy. She is a very happy kid and Kas has always helped her to have fun and be engaged with the world around her and does not find her disabilities in anyway a detractor from my child having a wonderful experience, Kas is patient and kind and an absolutely wonderful human being. Kas is always prompt and reliable and does a good job of following schedules and any special things that are needed, Kas is always happy to help with. Whenever we can get her, Kas is our first choice for Sitter because of what a wonderful job she does with my three-year-old. If it were possible to recommend to Kas any higher, I would do so.

Jack $22 per hour for 1 child

Hi! My name is Jack, I am 23 years old and born and raised in Seattle. I want to become a music teacher and in the winter will begin my classes for a teaching degree. Right now I am offering childcare, pet care, and house sitting. I am an older brother of a little sister and a baby brother so I’ve been watching kids and babysitting since I was 12. Outside of my own family, I babysat through high school, including large groups of kids (group of 6 kids all under 13yo) and have experience working with kids professionally in the Seattle public system and briefly at a public middle school in Oakland CA. I also love pets! If you have any furry friends who need some attention I have lots of experience with cats and dogs. I have fostered kittens and older cats including behaviorally challenged cats. I have experience with large breeds as my family owns a Rottweiler, and I have experience dog sitting behaviorally challenged dogs as well. Some special experience I have is with instrumental coaching and beginning music skills. I also have lots of experience outdoors fishing, hiking, rock climbing, I’d be happy to take adventures outdoors or go out for activities. Please feel free to ask any questions about my experience!

Greta 2 reviews
$25 per hour for 1 child
Booked by 2 families in Mercer Island, WA

Hi there! I am the mom of 2 high school kids. I have a Masters in Secondary Education, and during the school year, I run my own math tutoring business, from elementary to high school students. I have 8 years experience as an art and science teacher. I am working part-time as a nanny for infants and small children. I have a lot of experience with infants and toddlers. I am an active and attentive caregiver: I sing to, read to, play with, teach, and comfort the infants/kids I nanny. I participated with my own kids in coop preschool. I still incorporate what I learned in preschool into my tutoring and nanny work: encouraging positive behavior, calmly setting limits, asking children questions, and really listening to children. I enjoy being around kids. I am a swimmer, outdoor enthusiast (hiking, biking and bird watching), and enjoy spending time with my family outdoors.

Greta was an absolute lifesaver for our family. After working with multiple sitters and nannies, I can confidently say she was by far the best. She consistently went above and beyond, especially in caring for our daughter, who has special requirements. Greta and our daughter quickly became best friends—she was always excited when Greta came by. Greta supported us tremendously as new parents, offering thoughtful tips and advice when asked, and truly became part of our family. Even during our daughter’s “stranger danger” phase, Greta was someone she trusted and adored when others couldn’t calm her. We will absolutely continue to use Greta in the future and highly recommend her.

Rebekah $20 per hour for 1 child

Hello, I’m Rebekah 😊 I have almost 10 years of experience working with children in various settings. When I was in high school I taught dance to 3-10 year olds and had a consistent babysitting job. My undergraduate degree is in Elementary Education. I have worked in several formal and informal educational settings (day camps/overnight camps/after school programs/childcare centers). A couple of years ago I moved to Seattle and am now working full time as an administrative assistant. I’m looking for an occasional - to part time babysitting position. Some of my favorite movements working with kids include making crafts, exploring nature, fun science experiments and playing card games. I am currently only certified for Adult CPR in addition to general first aid. I have received Infant child CPR certifications in the past. After graduating college I received my preliminary teaching license. However, at the time I went to work in outdoor education settings. Due to this, my teaching license expired around 3 years ago. I have experience working with kids in Montessori settings. Also, I have a lot of experience caring for dogs and cats. Percy and Hercules are my cats and I am the main sitter for my sister’s two dogs.
