Booked by 46 families in Mercer Island, WA

Hello, I'm Fatuma, a student with a passion for working with children. In 2023, I worked as a camp aide teacher at the Pacific Science Center. Due to my religion, I cannot work with dogs; but willing to work with any other animals.I am capable of handling housework and running nearby errands. I've completed a first aid class, holding a valid certificate, and plan to retake the course for a refresher soon. Seeing the kids I work with grow and show their personality is the reason why I love being a babysitter/nanny. I enjoy reading, cooking and baking, going to the park, watching movies, going out to have fun, etc.

"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)."
