Booked by 6 families in Mercer Island, WA

Hello! My name is Unyoung. I love fostering curiosity, compassion and playfulness. Integrity and trust are sacred to me. Food and great conversation delight me and creative sparks are ticklishly fun. Besides the enriching experience as a mother, which has been the most important, I also have worked in retail, residential leasing, quality control and the restaurant industry. I would love to share time with a curious child or be an engaging conversationalist with the elderly. I also am very thrilled at the prospect of cat/dog/house sitting. I am available for date nights and have weekend flexibility as well. I hope to hear from you soon to see if your needs and my offerings would be an awesome match!

“We were so lucky to find Unyoung for a last minute babysitting job with our toddler! She made him feel at ease and kept him engaged for hours. Can’t wait to work with her again!”

Booked by 4 families in Mercer Island, WA

Hi- My name is Dylan! I enjoy partnering with parents to ensure children receive the nurturing, consistency, care, and fun they need. I am a kid at heart and love to get down on the floor (or up in a play structure) to play with kids, encouraging their imagination, doing age appropriate science and art projects, adventuring outdoors, and facilitating their brain development through play, reading, and singing. It is important to me to model empathy, respect, and acceptance with the goal of empowering children to solve problems. Additionally, I am very skilled at multi-tasking and time management to ensure the safety and well being of all children in my care. Biggest strength: I give kids the attention they deserve! I am regularly referred to by parents as the 'kid whisperer' or 'Pied Piper.' While some believe I have magical powers (especially toddlers!), in truth, I am simply present and attuned to their needs and wants, through the laughter and tears. Experience: I have over 15 years experience as a babysitter and nanny for children birth to 12 years, providing care for up to 5 children at a time in the family's home and traveling. Including extensive 24/7 care for parent work/fun trips, Philosophy: I feel strongly about following the family's routine and general style of parenting for consistency and a sense of safety for your kid(s). With that said, I engage a gentle parenting style and natural consequences rather than punishment, do not engage kids with screens (with minor exceptions), and love to help tidy, if you are open. Specifics: I have experience as a newborn night nanny, birth and postpartum doula. I have worked with single parent, blended, multiracial & LGBTQ+ families. I have worked with preemies, newborns, twins, neurodivergence (ADD/ADHD, autism, OCD), food allergies/special diets, and trauma (medical, bullying, and DV). Neurodivergence Experience: Nonverbal (with and without comm boards), toileting, care/support during meltdowns, sensory seeking, special food prep. Animals: I love them! Happy to pet, potty, and feed your fur family as well. Or ignore, in the case of an aloof kitty :-) Education: BA: Leadership & Human Services Antioch U - Seattle (2014) Infant/Child CPR/First Aid - 12/25 Newborn Care Specialist Certificate - 12/25 Work History: 10+ years in social work directly supporting homeless youth, mental illness and SUD in homeless adults, and medically fragile individuals. Happy to share ample glowing references!

“Dylan is wonderfully responsive and responsible and amazingly kind. He worked as night support for us with three babies in the house. We slept! Dylan also watched our very challenging 9 year old. We are so grateful for Dylan and how he relates to babies and young children. We would absolutely hire again!”

Booked by 1 family in Mercer Island, WA

Hello! My name is Tyleiyah. I grew up in a big family with many siblings and cousins, I'm very creative, and adaptable. As a big sister, I grew up raising my siblings which ultimately guided me down the path of childcare. I'm very passionate about kids and ensuring they are happy and healthy. I value critical feedback. With my experience with not only my family but also nannying for various families, I feel confident in my ability to care for your kids in the best ways possible. I am CPR certified, currently studying early childhood education, and have a valid drivers license. I am very open do doing more training if needed! Some areas I thrive in are potty training, arts and crafts, household chores, cooking, extracurriculars and nap time. Love all animals, especially cats and I'm able to take on additional responsibility for pets at no additional costs.

Booked by 3 families in Mercer Island, WA

Hi there! I currently work at UW in the College of Education and I’m looking for some part time work outside of my regular work hours. I've worked with kids my whole life. I'm the oldest of 7, and I've always helped out at the house. In the past, I worked as a camp counselor at an outdoor camp based in San Francisco. I got to work with kids 4-12 and teach them awesome things like kayaking, mountain biking, and SUPing. In addition, I have experience working as a nanny to an infant throughout college. I've always loved working with kids, and I love the constant energy! I will always prioritize your child’s safety and I have a background in child psychology from UW. Feel free to reach out if you have any questions and I’m so excited to get to know your family.

"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)."
