Will $25 per hour for 1 child

Hi! My name is Will. I have been an after teacher in South Korea for the last ten years and given the nature of theses roles, I have become adept at supervising and caring for school age children. I am responsible, transparent and orderly, but I like to have a fun side too. I also enjoy sharing knowledge with people of all ages about my travels around the world and in particular, my time in South Korea. Before living in South Korea, I was often trusted with looking after the neighbours' dogs or cats, and was available to help with chores people might have: moving, cleaning, gardening, errand running. Therefore, I have shown myself to be a trustworthy and attentive person to help take care of things. If you have any questions or queries, do let me know. Everybody's case is different so I am here to cater for your needs!

Hi there! My name is Anna and I'd love to chat more about this opportunity! Here's a bit about me :) I have a high school teaching certification and bachelors degree from Seattle Pacific University. I'm local to the area, have my own transportation, a non smoker and cpr/first aid certified. I have experience caring for infants, including feeding, diapering, sleep training, and engaging in age-appropriate developmental activities. I understand the importance of building a strong bond with a baby while also supporting the family's routines and parenting philosophy. I prioritize safety and communication at all times.

Luwam $30 per hour for 1 child
Booked by 1 family in Mercer Island, WA

Hi! My name is Luwam. I’m a caring and dependable caregiver with hands-on experience from raising my four children. I truly believe children learn and grow best when they feel safe, loved, and comfortable—and that is the kind of environment I always strive to create. I have completed a certificate in Early Childhood Education and have a genuine passion for helping children explore, discover, and reach their full developmental potential. I am patient, responsible, and committed to supporting families by providing attentive, nurturing, and reliable care. I am also certified as a school volunteer and chaperone, which has given me additional experience supervising children during school activities, field trips, and group events. I currently work with children with special needs as an assistant, and I am always willing to learn more so I can better support every child’s unique needs.

"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)."
