Anastasia $30 per hour for 1 child

Hi! My name is Anastasia and I’ve been caring for kids and families in different settings for almost a decade. I’m a toddler teacher transitioning into paraeducator work, and I’m looking to support families with child care, pet care, household help, and senior care. I started helping with kids around age 12, shadowing my nanny while she watched her friends’ children. In high school I regularly babysat two kids after school and during the summers (ages 1.5–5), and I also worked as a parents’ helper and date‑night sitter for another family from 2018–late 2019. In addition to private babysitting, I’ve worked in center-based care at The Goddard School with ages 2.5–4 as a floater, supporting multiple classrooms. As a toddler teacher, I’m very comfortable with big feelings, tantrums, and helping little ones with transitions and routines. I’m CPR/AED certified and have completed Bright Horizons trainings and other required early childhood courses. I’m comfortable with school pick‑ups, simple meals, light cleaning, play-based learning, and creating calm, structured routines. I also love animals. I have two cats of my own, I’ve done overnight dog sitting, and I help care for my parents’ two dogs. I’m happy to include pet care, walks, and basic house tasks in my visits. Families describe me as dependable, gentle, and very detail‑oriented. I’d love to get to know your family and see how I can help.

Evie $20 per hour for 1 child

Hi! My name is Evie and I'm currently a sophomore at Western Washington University studying Biochemistry. I am offering child care, pet sitting, and household services. I love babysitting and pet sitting for friends, and I have further experience through volunteer work with the Girl Scouts of Western Washington and Elevate Robotics Camp. My experience is focused towards toddlers and kids rather than newborns and infants. My responsibilities included tutoring, crafts, organization and management. I can cook, clean, and run errands. I can work with families with cats and dogs, and would be happy to work with more exotic pets if given care instructions.

"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)."
