Ainsley $21 per hour for 1 child

Hello! I am a student at Cal Poly Slo with previous childcare experience. I worked as a childcare attendant & teacher at Pro Club Bellevue, and am CPR & first aid certified. I love working with children and finding fun ways to spend a day with them. I love to get creative! Creating an enjoyable day for the kids is just as fun for me. From my time at Pro Club I am an excellent multitasker - watching 15 kids at once is no joke. I am happy to do other household errands and chores, and I am available any time. In a job, I am looking for something around 20-30 hours a week and for the summer.

Aslı $22 per hour for 1 child

Hi, my name is Asli and I'm currently living in Seattle. I offer child care, senior care, and household services. I absolutely love being a babysitter! I've been caring for newborns, infants, toddlers, and kids since I was 12. Additionally, I work as a household assistant, offering services like cooking, cleaning, and running errands. I have experience taking care of my own cousins so I’m comfortable with child care tasks such as cooking and other daily tasks. (I’m also an excellent bridge partner!) I’m a big fan of cats and I’m happy to work with families who have cats.

"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)."
