Shannon $40 per hour for 1 child
Booked by 1 family in Mercer Island, WA

Hi - My name is Shannon. I was recently laid off after working at Amazon for the last 6 years and am returning to childcare as I figure out my next career move. I am offering child care, pet care, senior care, and household services. I am the oldest of 5, with two siblings 10 years younger than me, so childcare was my inherited first job. I became the go to babysitter in my neighborhood until college. At 12 I started an apprenticeship with a dance instructor and taught children ages 2 to 14 for over a decade. Throughout college I ran the afterschool program at one of the schools in the Kyrene School District in Tempe, Arizona. I managed our “Kindergarten Club” to separate the younger kids and give them more individualized activities and attention. I instituted a reading program and have a lifelong passion for childhood literacy. I returned to childcare while getting my MBA from Seattle Pacific University and became a nanny to a two year old girl from 2[removed]. Before Amazon I was working as an interior designer and have a gift for organizing and decorating a home. I am available to run errands and help with household chores or even organize that closet you’ve been neglecting. I have the friendliest miniature long haired dachshund named Fonda and would love to care for your animals as well!

Husneya $35 per hour for 1 child

As the oldest daughter in a family of seven, caring for others has always been a big part of who I am. I helped raise my younger siblings, who are now between the ages of 11 and 14, which gave me years of hands-on childcare experience from a young age. I have also worked with children in a school in Alberta and currently work with Safe Space Childcare Services, where I care for children of all ages. These experiences have taught me how to create a safe, fun, and supportive environment while meeting each child’s individual needs. I am patient, nurturing, reliable, and genuinely love spending time with kids. Whether we’re playing games, helping with homework, reading stories, or enjoying creative activities, I always strive to make children feel happy, comfortable, and cared for. I also have a passion for cooking and enjoy preparing nutritious, homemade meals and snacks when needed. I look forward to supporting your family with dependable and compassionate 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."

"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)."
