Anairis $26 per hour for 1 child
Booked by 1 family in Mercer Island, WA

Hello my name is Anairis but you can call me Ana :). I am a full time nursing student with 2 years nursing assistant experience with older adults. Working with older adults has been a joy, I love building strong connections and being a reliable person for them. I’m able to assist with activities of daily living. I occasionally babysit my nieces and nephews whose ages range from 10 months- 10years. I’m currently a babysitter for a family, taking care of a 2,5, and 8 year old. I hope to work in pediatrics because children are curious and fun to be around. I’d be happy to tutor as well. I can get creative with dancing, story telling, cooking and crafts. I have 1 dog who is 9 years old but I love all pets! I am BLS/CPR certified, first aid certified, and nursing assistant certified. I have a driver license and car. I love interacting with people of all ages and pets!

ifttu $30 per hour for 1 child

Hello, I'm Ifttu, a 24-year-old student at Highline College, and I'm excited to offer my child care services! Growing up in a big family with eight nieces and three nephews of all ages, I've had plenty of hands-on experience. My mom ran a daycare, and I spent years working alongside her, which really shaped my child care skills. I also spent summers during high school as a frisbee counselor, where I not only taught kids how to play but also emphasized the importance of staying active and being themselves. After that, I found my calling as a nanny for some amazing families in Seattle. It's been such a rewarding experience! When it comes to child care, I love bringing out kids' creative sides through art, music, and play. I'm a big believer that an active child is a healthy child, and I'm always up for reading time too! My main goal is to make sure every child in my care is not only learning but also having a blast and feeling valued. I'm flexible with my hours and more than happy to chat about wages that work for everyone. Thanks for considering me—I can't wait to meet your family!

Sarah $22 per hour for 1 child

Hi, I’m Sarah and am a senior at the UW studying Geography and Information systems (GIS). I’m born and raised in Seattle and have been working with kids for the past few years. I’ve worked at a daycare, where I spent a year specializing in the toddler (2-year-old) room, as well as volunteering at elementary summer camps. Right now, I spend my weekends teaching a program for 8-12 year olds, and last year, I worked with a nonprofit running after-school activities for kids who needed extra support. Family is important to me, last year, I had the joy of helping care for my infant nephew when my sister welcomed him into the world. From infants to pre-teens, I love connecting with kids through play and learning. When I’m not babysitting or studying, you’ll find me curled up with a book or when I can find the time exploring new hiking trails.

"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)."
