Hi - My name is Emily and I’m currently a sophomore student at the University of Washington. I am offering child care and pet care. My most recent babysitting experience was for a family friend’s toddler for about a year periodically. I also have a younger brother who is 6 years old who I spent a majority of my time babysitting as he grew up. I feel as though I have a good amount of experience in each stage and age. I am very adaptable and a quick learner to accurately adjust to each child I babysit and meet parent expectations. I grew up owning multiple dogs and most recently a cat. I love animals and am capable of checking up on them and assuring their necessities are met.

"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)."
