Booked by 5 families in Mercer Island, WA

Hi! I’m Amber and I’m a teacher that’s looking to help out families after school and on weekends! I’m interested in providing childcare, pet care, and/or household services! I’ve been teaching for the last 7 years in public schools. Prior to teaching I worked in childcare running the infant classroom and floating amongst the toddler-age classrooms. I also have experience working with children in special education so I feel very comfortable working with all ages and ability levels! Both my educational and work background almost exclusively revolve around children and have allowed me to develop an excellent set of knowledge and personable skills for working with kids. I feel very comfortable and confident caring for all ages!

“Amber is fantastic. She’s communicative, prompt, and easy to work with. She’s flexible and has tons of practical experience working with children. The kids had a great time with her and want her back soon! ”

Hi, I’m Lydia Grace! I recently graduated from the University of Washington with a BS degree in Biology and am taking two gap years before attending medical school with a focus in maternal-child health. I am also certified in CPR/First Aid for Adults, Children, and Infants, so safety and reliability are always my absolute top priorities in the household. I have worked as a childcare provider for 4 years, gaining extensive experience across a wide range of age groups and developing the skills to confidently care for up to four children at once. I care deeply about contributing to children’s growth and well-being, and I recognize the vital importance of age-appropriate activities. I love leading kids in engaging crafts, outdoor play, and reading to support their ongoing developmental milestones. Additionally, I have a background in tutoring and am always happy to help with homework, especially in STEM subjects and Spanish. I am also completely comfortable preparing healthy meals for the kids and keeping the house tidy and organized. I look forward to bringing a blend of fun, developmental engagement, and reliable, safety-focused care to your family! Please feel free to reach out with any questions. :)

I have had several years of experience working with children of all ages. Working with children is something that I am very passionate about. I graduated from Seattle University Law School and am available currently studying for the bar exam. I am looking for a part-time position and have flexible study hours.

“10/10 would recommend! Kailey babysat our daughter along with two of our friends’ children and it went so well! The girls had a blast and felt comfortable with Kailey. It’s awesome that she charges a reasonable price for multiple kiddos. We’re all looking forward to next double date night knowing we have someone to watch the kids.”

Booked by 6 families in Mercer Island, WA

Hello families, as my contract is coming to an end soon, I am searching for a new part-time role in the mornings. Availability: 20-30 hours weekly, between 6 AM and 12 PM. A little bit about me: - I have a reliable car. - Clean driving record. - CPR certified. - Non-smoker. - Up to date with all vaccines. - Bilingual (Portuguese and English). - Very outdoorsy. I am enthusiastic, energetic, caring, and patient. I am also very punctual and love pets. North Seattle is preferable, but I’m happy to travel further for the right fit. If you’d like more information, please don’t hesitate to contact me. Thank you!

“Inaye was so bright and cheery! She was great with my autistic son! I would highly recommend her for anyone and especially for kids with special needs. Thank you Inaye!”
