I studied Early Childhood Education and will soon continue my studies in Therapeutic Pedagogy. I am currently in the United States with the goal of improving my English while continuing to grow professionally in the field of child development. My English level is basic, but I am constantly learning and improving. I have more than 8,300 hours of childcare experience and am trained to care for children from newborns to 10 years old. My experience includes working in a Montessori school, church children's programs, and social work supporting children from underserved communities. I am passionate about helping children learn, grow, and feel safe. I enjoy outdoor activities, creative play, reading, and creating a positive and nurturing environment. I would be delighted to be a supportive, caring, and responsible presence in your child's life.

Hi, my name is Kim. I’m a warm, kind-hearted, and caring person who loves spending time with children and sharing in their youthful, energetic spirit. I’m a reliable and responsible adult with good judgment and many years of experience caring for babies, toddlers, and young children. I currently care for several families on a regular basis during the week. I am currently looking to connect with one more family in the Bellevue or Newcastle area. I’m self-motivated, highly organized, and also a great cook — happy to help with light meal prep if needed. I value working with families who see their nanny as part of the family, and I’m looking for a long-term position where I can build lasting bonds with the children. I have an inquisitive mind, a love of learning, and a genuine desire to help out wherever needed around the home. I’m easygoing, dependable, and always eager to lend a hand.

“Kim took care of my mother. First time worked out well. Used translator app.”

Hi - My name is Tracy and I reside in Bellevue, WA. I am offering child care, and household services. I am searching for something temporary or part-time due too my current enrollment at the Bellevue College. Working with children has always been something I genuinely enjoy. I spent over three years as a preschool teacher, managing my own classroom of approximately 10 children and creating a safe engaging, and nurturing environment for learning and growth. In addition to teaching, I have worked as a private nanny since I was 18 years old and have experience as a summer camp counselor. As the youngest of four siblings and an involved aunt, I've had the opportunity to care for children of all ages, from newborns to preteens. My childcare experience includes school and activity transportation, homework assistance and tutoring, meal preparation, bed time routines, and even working as a travel nanny. I am currently CPR certified and hold a valid Washington State Enhanced Drivers License, allowing me to safely transport children when needed. I also have a Washington State Food Handler's Permit and am trained in proper food safety and meal preparation practices. Beyond childcare, I have experience working as a household assistant and am happy to help with cooking, light housekeeping, organization, grocery shopping, errands, and other household tasks that help keep a busy home running smoothly. In my free time, I enjoy spending time outdoors, especially hiking or paddle boarding. My perfect day includes a good book, a picnic, and body of water to swim in. I am easy going, dependable, and believe in finding joy in life's small moments. I strive to bring patience, positivity, and reliability to every family I work with. I would love the opportunity to support your family and help make your day-to-day life a little easier.

“Patient, kind, thoughtful and collaborative. My son took to her within 1 minute of meeting! Will definitely work with Tracy 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."
