Booked by 7 families in Mercer Island, WA

Hi, I’m Eden! I’m currently pursuing a degree in Nursing, and caregiving has always been at the heart of who I am. With over 8 years of experience caring for both children and seniors, I bring compassion, patience, and reliability to every home I work in. I’ve previously worked as a teaching assistant in a kindergarten classroom, where I developed a love for supporting young learners. I’m certified in both CPR and as a Home Care Aide (HCA), so safety and well-being are always top priorities for me. I come from an Eritrean-Ethiopian background and was raised in Kenya, which has given me a rich cultural perspective and the ability to speak multiple languages. If you're interested, I’m happy to teach your children languages or share cultural experiences. I'm also comfortable around pets and open to assisting with light housekeeping. My goal is to make your life easier while providing attentive, loving care to your family. Let’s connect—I’d love to learn more about how I can support your household!

Dear Families, I am pleased to introduce myself as Berry. I have a passion for spending time with children and have gained experience babysitting my cousins for the past three years. Additionally, I have worked in a daycare for an extended period, which has equipped me with the necessary skills to take care of your child. I am also willing to provide household services to ensure that your family's needs are met. My love for kids motivates me to pursue this job, as I believe that being a part of a child's growth and development is a rewarding experience. With my experience ranging from infants as young as 3 months old to children as old as 9 years, I am confident in my ability to provide quality care. I am a patient and caring individual who is passionate about learning and sharing my knowledge with others, especially when it comes to helping kids grow and develop. Furthermore, I am comfortable with pets, and I am fully vaccinated, ensuring that I am equipped to provide a safe and healthy environment for your child. I look forward to the opportunity to work with you and your family.

“Berry was amazing and did a very good job watching our 4 year old. She played with him, engaged with educational activities, and cleaned up when she was done for the day. She took him outside for fresh air and made him fresh lunch. Overall, she met and exceed our expectations while we worked from home. I look forward to another day when we need backup care so we could request Berry again!”

"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)."
