Hi, My name is Alicia! I've been babysitting for 10 years now and it never feels like work to me because it's always fun! I've babysat kids in all different age groups, from 8 months to 10 years old. My favorite things to do while babysitting are going to the park, coloring, reading books, playing outside games, like tag. Pretty much anything to stay active and have fun.

Booked by 26 families in Mercer Island, WA

I'm a retired homemaker who has successfully raised three kids in this area. I live with my husband and 2 small dogs in Bellevue. We have three grandchildren under the age of 12, they live locally and we see them frequently! I love kids, people and pets and I like to help. I have many years experience as a parent, and have experience being a grandparent too. I can sit, tutor, play and cook. I enjoy running errands and I take direction well. Kids like me, and I'm good with babies too. In my spare time I enjoy reading, baking, board games, shopping, walking the dogs and babysitting.

“Dina was very professional and great with consoling my 3 week old newborn and spending time with my 3 year old. He really loved talking with her and was sad for her to go. It was so nice to have her help!”

Hello! My name is Jessica. I’m 26 and have been a preschool teacher since 2022. I am currently available on occasional evenings or on the weekends. I enjoy following children’s interests, acting playful and silly, and being actively engaged in their play. I love being a part of children’s learning and development, and seeing them express their unique personality! I always strive to connect with each child and make them feel safe, loved, and valued. My favorite activities to do with children are arts and crafts, pretend play, outdoor play, reading, puzzles, board games, and playing hide and seek. I also have experience working with toddlers and elementary-aged kiddos — providing care, tutoring, and leading developmentally-appropriate activities. Through UrbanSitter, I have cared for children from 2-11 years old. You can always expect clear communication, safety and entertainment for your child, and respect of your house rules and expectations. Feel free to reach out, I’m excited to get to know you!

Hi, my name is Helen! I moved to Seattle after high school and completed my college career here. I've worked most of my life with children and I love it. I love how much character their personalities already have and the energy and joy they bring to the table. I've worked personally for families as well as done babysitting for events where childcare is provided; which has given me a chance to watch wide variety of ages. The imagination that children possess is something to behold, nothing is simply ever just a 'toy' but has a whole story to it. That's a little bit about me! I hope to meet you in person soon!

Hey there, I’m Julia – Ready to make your home life a little smoother. Hi, I’m 29 years old and have been working with kids since I was 16. I’ve cared for babies, toddlers, school-aged kids—you name it. I’m also a college student with a background in healthcare and a lot of experience helping families keep things running smoothly. I’ve worked in a woman's hospital, trained as an EMT (and worked in the field for two years), most recently spent three years as an Au Pair in the U.S., helping families manage everything from busy school mornings to bedtime routine - and even running errands that they don't have time time. Here’s what I can help with: - Morning routines, breakfast, and school prep. - Keeping the house clean and organized. - Grocery runs, errands, and laundry. - Meal prep and dinner help - Picking up kids, driving to activities, and evening wind-down I’m extroverted, dependable, and love getting kids engaged with creative games, crafts, and outdoor play. I also understand the importance of helping parents feel supported and stress-free. If you’re looking for someone who can jump in and make your home run a little smoother, I’d love to connect.
