Booked by 2 families in Mercer Island, WA

i have been working with kids for over 10 years, working with all different ages from 6 weeks old to teens! I was a nanny for years, including being an au pair twice. I have created preschool - style curriculum, worked with families who limit screen time, and adore playing pretend! I have also been a teaching artist in children's theater and a camp coach for circus skills. I love comedy, clowning, storytelling, the outdoors, exercise, and doing crafts. I am an advocate for autistic children and kids with ADHD. I have worked with so many neurodivergent kids, have taught neurodivergent-forward improv classes and I have co-created and facilitate a workshop for educators on how to create a neurodivergent-friendly classroom.

“Karly made sure to ask questions and understand how to best care for our kid! She got him to bed and made sure he was entertained while we got to have dinner outside the house. Would definitely recommend her and already have her looking after our child on Friday!”

$23 per hour for 1 child

I bring years of hands-on caregiving experience across multiple areas. I have a dog who is going on 12, and I’ve been dog sitting for years, ensuring pets are fed, walked, played with, and happy. I understand the routines and individual needs that keep animals comfortable and content. When I lived in Washington DC, I worked with a few families caring for children aged 3-10. I made sure the kids stayed in their routines, ate their meals, and had engaging activities throughout the day. I played games with them and read to them before bedtime, creating that calm transition into sleep that parents appreciate. What makes me a great caregiver is my reliability and attention to the small details that matter—whether it’s remembering a dog’s favorite walking route, a child’s bedtime story preferences, or maintaining the structure that helps everyone feel secure. I’m patient, observant, and genuinely enjoy creating a positive environment where both kids and pets can thrive.

“She was so great with my kids! She kept them busy, playing, and having fun without just putting them in front of a screen, which I really appreciated. She’s naturally engaging, easy to be around, and you can tell she genuinely enjoys being with kids. My kids were happy, I felt comfortable, and I would absolutely trust her with them again!”

Zakhona $30 per hour for 1 child

Hi families! My name is Zakhona and I’m originally from South Africa. I’ve always had a natural love for kids. I started caring for my younger cousins when I was the oldest grandchild at home, and that’s where my passion began. In 2022, I started working with families outside my own and have cared for children of different ages since then. I’m currently an au pair, taking care of a baby I’ve been with since she was 6 months old. I handle everything from feeding and naps to playtime and fun activities that support her development. I love doing outdoor walks, dancing, reading stories, and getting creative with crafts or sensory play. I’m also happy to help with tidying up after play. I’m warm, patient, and dependable and I treat every child as if they were my own little sibling. I’d love to bring my care and experience to your home and support 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."

"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)."
