Anna-Marie $25 per hour for 1 child

Currently working in a preschool as a substitute, I have an open schedule here and there! Overall, I have a background of five years working at summer camps, two years in an after-school program, and extensive babysitting experience. I bring a wealth of knowledge in childcare. I enjoy connecting with children through arts and crafts and am known for my friendly and attentive personality. I’ve worked with children of all ages, including those with special needs, and I’m well-informed about diverse developmental needs, ensuring every child feels safe, respected, and encouraged to express themselves. In addition to my experience with children, I have a strong background in caregiving for adults with special needs, which has deepened my ability to provide patient, compassionate, and attentive care. Additionally, I have experience taking care of pets of all kinds, making me adaptable to any household situation. My goal is always to create a nurturing, enjoyable environment where both children and parents feel confident and comfortable.

Booked by 11 families in Mercer Island, WA

Hi! I’m Laura, a 23-year-old caregiver with 5 years of experience working with children of all ages, from newborns to school-age kids. I genuinely love spending time with kids and creating a safe, fun environment where they feel comfortable and happy. I enjoy doing crafts, reading stories, going on walks, and finding activities that keep kids engaged and active. I’m patient, attentive, and always try to match each child’s personality and needs. I’m also a big animal lover (especially dogs!), so I’m very comfortable in homes with pets and happy to help with pet care too. In addition to childcare, I can help with light cleaning, organizing, and running errands to make your day a little easier. I’m reliable, responsible, and always aim to make families feel they can trust me with their home and their kids.

“Laura did a wonderful job taking care of our daughter. Laura was very communicative, helpful, punctual, and professional, and got along really well with our five year old. She got her to take a nap and a bath (two things our daughter isn't super fond of), and she conversed and played well with her. We would highly recommend Laura to other parents, and hope we can have her come back again to take care of our daughter. ”

Hi there, My name is Selay. I’m 30 years old and originally from Turkey. Spending time with babies and children is a true passion of mine. It brings me great joy to witness their curiosity as they explore the world around them. Caring for children has always been an important part of my life, not just as a job, but as a natural part of my family life as well. As the eldest child, I took on caregiving responsibilities at a young age. While my parents were working full-time, I was closely involved in caring for my younger sister from the time she was a baby, and I also helped look after many of my cousins. Growing up surrounded by children taught me so much and shaped me in many positive ways. I came to the United States as an Au Pair. I worked with the same family for three years, and during that time I also had the opportunity to work regularly with other families. Through these experiences, I have cared for children of nearly all age groups, including newborns. Over the past five years, I have developed extensive experience providing attentive, nurturing, and safe care for newborn babies during their most delicate and important early stages. With my current family, I began caring for their baby when he was just 1.5 months old, and we have been together throughout his entire growth journey. He is now 2 years old, and as he will soon be starting daycare, I am looking for a new position. My experience with newborns also inspired me to deepen my knowledge through professional training. I have completed birth and postpartum doula training, which strengthened my understanding of newborn care, postpartum support, and the emotional and practical needs of families during the early months. I am also currently completing Montessori teacher training. This has helped me better understand child development, independence, respectful caregiving, and how to create an environment where children can learn and grow at their own pace. Through all of these experiences, I’ve come to realize how fulfilling it is to work with children of all ages. Teaching them while also learning from them is truly a magical experience. If you’re interested, please don’t hesitate to reach out. I would love to talk about how I can support your family. Thank you, Selay

“Selay was great - she showed up on time and had great energy with our kids. Our kids enjoyed time with her and she put our kids to bed smoothly so we got to enjoy a quiet home when we came back!”

I genuinely enjoy caring for children and creating a safe, fun, and nurturing environment where they can learn and grow.

"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."
