Jade was wonderful! I instantly felt comfortable with her. She watched my 5 and 6 year old in an outdoor setting, due to Covid. She sent me a photo of them looking for bugs and playing, unasked. She had great communication, a wonderful attitude and excellence presence with the kids. My daughter told me she had missed me while I was gone and that Jade was very kind and comforting. Shortly after we got in the car, she asked if we could hire Jade again.

Hello! My name's Emily, and I'm a recent graduate from the University of Washington. I've mainly worked with children in the K-5 age range, but I'm very open to babysitting children of younger ages as well! Most recently, this last summer I was employed as an Assistant Instructor at IslandWood, an environmental education day camp on Bainbridge Island. I've also worked as an After-School Counselor at Wedgwood Elementary School. Additionally, I have past experience as a babysitter with middle-school aged children. I have a Honda CR-V with four seats (three in the back seat, one in the front seat if old enough) if any type of driving is needed. If you would like to talk further or have any questions, feel free to contact me!

The boys loved Emily. She did a great job.

*looking for full time-part time regular positions for this summer starting July 1* Hello/hola! My name is Marilyn, I’m a 24 year old, bilingual (English/Spanish), student with over 6 years of childcare and senior care experience. I have 3 years of experience working for the YMCA as a before/after school instructor, summer camp counselor, and a early learning center floater. I have also nannied for three families and have been an on call babysitter for five others. I live in the Issaquah/Newcastle area and would love to find families to provide childcare for! I genuinely enjoy it and am working to have a bit of money while in nursing school at Bellevue College. I have many wonderful references and would love to chat if interested. Pay range negotiable and cash is preferred.

Our kids really enjoyed having Marilyn spend time with them! She was on time, easy to talk too, and a great communicator. She also agreed to house sit and keep an eye on our dogs while we are away for a night.

"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)."
