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.

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.

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!

I have been babysitting and working with kids since I turned 13 and started walking to babysitting jobs in my neighborhood. I love going on walks, reading, and doing crafts! I currently work at a general contractor coordinating our high school and college internships. I am looking for occasional nanny jobs.

“Emma was great! On time, engaging with our son, and listened well to instructions for the day. She was responsive and had a rave review from the kiddo when we got home!”

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!

"We were incredibly grateful that Maya was able to help us out with a last-minute childcare emergency. She matched our 9-year-old's energy with arts & crafts, some quiet reading, and a walk around the neighborhood. We'd have Maya back in a heartbeat!"
