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.

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.

Hi, I’m Summer! I’m currently a part time nanny for twin 5 year olds and looking to pick up extra hours while I’m on break from school. I study Speech Pathology online and got certified this year to teach kids yoga which I’ve been loving and teach on occasion. I also have experience teaching swim lessons and have several years of childcare experience with kids of all ages, including multiple sets of twins. I’m CPR and First Aid certified and enjoy keeping kids engaged with fun activities that help them learn and grow.

Summer was fantastic! She was professional, warm and engaging and my 10 year old daughter loved her from the second she walked through the door. Will definitely hire Summer again!

Booked by 10 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.

"We absolutely LOVE Isa — our family was so fortunate to have found her through UrbanSitter. I'm a first-time mom, and it took me a long time to find a full-time nanny I could trust to care for our sweet infant boy. Our boy connected with her immediately, and we couldn't have asked for anyone else to care for him. Her calming presence was also perfect for parents like us who work from home. We feel so lucky UrbanSitter helped us find someone who has truly become a part of our family."

"I was so stressed about finding a part-time nanny for my 14-month-old son, who has moderate separation anxiety and hadn't been left with anyone but family before, but we were both immediately at ease in Buhay's presence. Her empathy and commitment to understanding child development are apparent in every interaction I've witnessed between her and my toddler. I feel very lucky to have found her."

"Erna watched our now 5 year old daughter and 3 year old son for a few years. She is punctual, responsible, honest, and playful. What we appreciated most was that she was thoughtful in ensuring that we had a little break; for example, when the kids were clingy, she was able to divert their attention with games or songs or walks to the park. We felt very comfortable leaving our kids with Erna because of her caring nature and experience that spans a decade (including being a live-in nanny)."
