Gillian $28 per hour for 1 child

I am a passionate care provider. I bring this passion with me to every job that I do. I am creative, and fun, but also bring balance, and stability. I love working with children in a variety of settings. I have had the privilege of working with the same families for over ten years. I have also worked with children on the autism spectrum, and other special needs. Most of all, parents can trust me with their children. This is of upmost importance when choosing a care provider.

Tanya $15 per hour for 1 child

My name is Tanya, and I am the mother of two (daughter 17 and son 3). I would like to put my name out there for childcare for your little ones. Ideally, your child(ren) could come to my house, but I can also go to yours. I do have my 3 year old little guy who would be there or come with me. I am located in Fairwood Greens community in Renton, WA, and my home is a smoke free and no pets. All of us (except my 3 year old) are fully vaccinated. I can help with date nights, or I am even open to exploring an ongoing thing if there is someone who works nights or weekends and needs help. I know it can be hard to find childcare for those off hours. I have every other Friday off as well so a daytime slot could work there as well. I am happy to go over timing in more detail though. If you are interested and would like to chat more and get to know me beforehand, feel free to message me. We could even meet up at the park for a little meet and greet before you make any decisions. 😊

$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).

ā€œKas 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.ā€

$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.

ā€œGreta 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 ā€œstranger dangerā€ 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.ā€
