Booked by 1 family in Mercer Island, WA

Hello! My name is Tyleiyah. I grew up in a big family with many siblings and cousins, I'm very creative, and adaptable. As a big sister, I grew up raising my siblings which ultimately guided me down the path of childcare. I'm very passionate about kids and ensuring they are happy and healthy. I value critical feedback. With my experience with not only my family but also nannying for various families, I feel confident in my ability to care for your kids in the best ways possible. I am CPR certified, currently studying early childhood education, and have a valid drivers license. I am very open do doing more training if needed! Some areas I thrive in are potty training, arts and crafts, household chores, cooking, extracurriculars and nap time. Love all animals, especially cats and I'm able to take on additional responsibility for pets at no additional costs.

Booked by 3 families in Mercer Island, WA

Hi there! I currently work at UW in the College of Education and I’m looking for some part time work outside of my regular work hours. I've worked with kids my whole life. I'm the oldest of 7, and I've always helped out at the house. In the past, I worked as a camp counselor at an outdoor camp based in San Francisco. I got to work with kids 4-12 and teach them awesome things like kayaking, mountain biking, and SUPing. In addition, I have experience working as a nanny to an infant throughout college. I've always loved working with kids, and I love the constant energy! I will always prioritize your child’s safety and I have a background in child psychology from UW. Feel free to reach out if you have any questions and I’m so excited to get to know your family.

Booked by 2 families in Mercer Island, WA

Hi, I’m Sammie, and I’m currently offering childcare as well as assistance with household services and pets. I currently work as a teacher at an outdoor school. I have two years of experience as a preschool teacher in an outdoor preschool, and have been working with kids as a teacher, tutor, babysitter, and guide for over ten years. My style of teaching and babysitting is child lead, informed by kids interests and passions. I obviously love involving outdoor play, but also love art, cooking, and other kinds of projects as well.

“She is calm and cheerful and my kids love her! She approaches them at their level and gets them to open up, and they are comfortable with her. Would definitely hire her again.”

Booked by 1 family in Mercer Island, WA

I currently work at a daycare with ages from 4 months-3 years. I also have nannied with ages up to 5. I also have had experience with house sitting and dog watching with multiple dogs at a time.

“Amia was our first non-family babysitter, so we were a little anxious, but she made us feel at ease instantly. She immediately clicked with our daughter and was very tolerant of our crazy dog. Our daughter had a lot of fun and was sad to see her go. We will definitely be using her again!”

"Johanna is AMAZING! My two boys love her - she does everything from amazing arts & crafts, to helping with homework, to getting them playing outside! She also drives them and does everything involved with after school activities: packing snacks, getting the right gear, etc."

"When we hired Amani, we felt like we hit the jackpot. We were very lucky to find her on UrbanSitter at the beginning of school year. She was picking up kids from school, taking them to afternoon activities, helping them with assignments. She prepped food for them, helped organize their closets and keep their spaces neat and orderly. We would hire her again in a heartbeat."

"Caitlin has been such a lifesaver for our family. We hired Caitlin to help with the after school routine. The kids took to her instantly. She does it all - school pick ups, dinners, baths, lunch making, clean up, etc. She has really helped make a busy time so much easier for us."
