Jessica $25 per hour for 1 child

Hello! I’ve recently quit the corporate 9-5 and am going back to my roots in childcare. I was a babysitter and swim instructor in my teens to early 20s before I entered the corporate world and loved it! I was a career where I can see the impact I make, however small or large that impact will be; in other words, I want to help!

Keira $17 per hour for 1 child

Hi! My name is Keira. I’m a dependable, patient, and caring babysitter with real-life childcare experience as a mom to my four-year-old daughter. Being a parent has taught me a lot about patience, safety, and creating a fun and nurturing environment for kids. I truly enjoy spending time with children and keeping them engaged with activities like arts and crafts, reading, playing games, going on walks, or visiting the playground. I also understand the importance of quieter time for things like movies, books, or relaxing activities. I know how important it is for parents to trust the person caring for their child, and I take that responsibility seriously. My goal is always to make sure children feel safe, happy, and comfortable while their parents are away. I’m responsible, attentive, and genuinely enjoy helping families. I would love the opportunity to care for your child and support your family

Naomi $25 per hour for 1 child
Booked by 1 family in Mercer Island, WA

Hi my name is Naomi and I'm new to the Seattle area ! Originally from Spokane, I'm the middle child of 9 siblings, so I'm all too familiar with raising, watching, and caring for kids. There's nothing like the joy that children give and I am so eager to be a part of a family, since I sadly moved away for mine to pursue my career. I am a DJ and have DJed for about 5 years now doing a variety of different events. This profession keeps my days completely open and are waiting to be filled up ! I played college basketball and sports have always been an integral part of my life, I love to play, read, and learn; and indulge in anything creative. Whether it's music, drawing, painting, photography or fashion, my gravitation to the arts remains in my admiration for art and beauty in general. My goal for your children is to enhance their love for life and appreciation for what's around them through organic human interaction and care.

"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."

photo of quoted parent Eric

"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)."
