Booked by 2 families in Mercer Island, WA

Hi, I’m Sammie, and I’m currently offering childcare as well as assistance with household services and pets. I currently work as a teacher at an outdoor school. I have two years of experience as a preschool teacher in an outdoor preschool, and have been working with kids as a teacher, tutor, babysitter, and guide for over ten years. My style of teaching and babysitting is child lead, informed by kids interests and passions. I obviously love involving outdoor play, but also love art, cooking, and other kinds of projects as well.

She is calm and cheerful and my kids love her! She approaches them at their level and gets them to open up, and they are comfortable with her. Would definitely hire her again.

Booked by 1 family in Mercer Island, WA

I currently work at a daycare with ages from 4 months-3 years. I also have nannied with ages up to 5. I also have had experience with house sitting and dog watching with multiple dogs at a time.

Amia was our first non-family babysitter, so we were a little anxious, but she made us feel at ease instantly. She immediately clicked with our daughter and was very tolerant of our crazy dog. Our daughter had a lot of fun and was sad to see her go. We will definitely be using her again!

Booked by 4 families in Mercer Island, WA

Hi! My name is Isabel, I’m 22 years old and I’m from Colombia. I currently take care for three wonderful girls while studying Systems Engineering so being organized and responsible is a big part of my daily routine! Being a babysitter is something I genuinely enjoy. I have over 2,000 hours of experience working with kids of all ages. I feel confident handling daily routines like getting them ready, preparing simple meals, pick-ups and drop-offs, bath time, bedtime, and of course lots of playtime and love! I always do my best to create a safe and fun environment for the children I care for I also have experience caring for seniors. I was very close to my grandmother and loved spending time with her - going for walks, cooking together or simply keeping her company I also love animals! Cats have a special place in my heart but I’m happy to care for dogs or any other furry friends. I’m also available to help with light housework and organizing if needed

Isabel did a great job taking care of our five year old daughter, who had a wonderful time. They played outside, baked, and talked. Isabel was punctual, communicative, and friendly. We hope to have her take care of our daughter in the future, and would highly recommend her to other parents.

Erin 1 review
$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!

"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)."
