Booked by 10 families in Mercer Island, WA

Hello I am from Brazil, I came here to the USA through an exchange program to learn a new language and new culture. I am passionate about what I do, I love travel, photography, painting, and books. I cared for children of various ages and assisted with feeding, dressing, and daily activities. I believe in creating nurturing, safe environments to promote emotional, social, and intellectual growth. I provided safe transportation to and from activities and events. My strength is to engage with children on an individual basis to build positive, trusting relationships. I don't mind supporting household operations by completing laundry, cooking meals, and performing light cleaning.

Hi! My name is Farhiya and I’m a patient, caring, and responsible caregiver with strong experience working with children of all ages. I’m great with infants, toddlers, and school-age kids, and I love creating a safe, fun, and structured environment.I have hands-on experience helping at my family’s licensed daycare, which has given me a lot of practical skills—like managing routines, supporting learning, and caring for multiple children at once.

"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)."
