Booked by 1 family in Mercer Island, WA

Hi! I’m Seila, a University of Washington graduate with a background in public health and extensive experience working with children. I’ve worked as a substitute teacher, instructional assistant (in both the U.S. and abroad), and tutor, supporting kids from toddlers to middle school. I’m especially great with younger children—I’m patient, attentive, and naturally warm, while also providing structure and consistency. I also have strong experience with middle schoolers, supporting their learning, communication, and behavior in a calm and respectful way. I love engaging kids through play, reading, and creative activities that support their development. I’m reliable, organized, and happy to help with routines like meals, naps, and light tidying. I take pride in creating a safe, positive environment where children feel comfortable and supported.

Seila was great with my 10 y/o daughter. I highly recommend her.

"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."

Kamilah W., mom of one

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)."
