Hi I am a ballerina living in Bellevue but willing to travel to around Seattle areas. I am an eldest daughter and have a lot of experience with taking care of my sibling and other kids. I have helped take care of kids ages 2 months - 14 years. I love working with kids and spending time with them. I have a car and am able to drive as needed. I am a very safe driver and have never received a ticket or gotten in a car accident. Please reach out for with any questions! :)

Elise showed up on time and my son really enjoyed playing with her. She made sure his bedtime routine was followed and got him to bed on time.

I have always had a passion for working with and taking care of children. I am the baby in my family, but it was my biggest joy being able to watch after my 5 younger cousins growing up. I think that is what sparked my interest. I was a youth counselor one summer in grade school, my first job I worked as a tutor for Kumon Learning Center, tutored a family friend's son for over a year, worked as an assistant for special needs children and adults. The start of covid I worked for College, Nannies, & Sitters, and at a preschool with children ages 1-5. During covid I moved to Cle Elum and nannied for a family of 4. When I moved back I worked for another preschool/daycare. I am extremely positive and patient, I am also very attentive and professional. I put the children's needs first, and love to build friendships that leave a lasting impact. I am a great listener and I love to interact. I will teach your children how to be responsible and polite, yet still be their silly, creative selves.

"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)."
