I have 8 years of consistent childcare experience, including 3 years as a healthcare assistant at a children’s hospital and a part time nanny for a family of six kids (ages 0-16). I’m responsible, reliable, and promise to keep your kiddos safe and engaged. I’m passionate about getting outdoors and introducing kids to fun, healthy activities. I respect family routines and am ready to adapt to your needs. Looking forward to meeting your family and making life a little easier for you! **late cancellations (within 12 hrs) I still charge half the booking amount**
“Sydney was amazing! Put us at ease immediately as it was our first time leaving the little one with a sitter. She was kind, caring and kept in constant contact with updates throughout the night. ”
Hi! I'm Maria. I currently work in the automotive industry while going to school for my teaching degree. Before that, I spent three years as a teacher's assistant with the Renton School District. Feel free to message me with any questions! :)
“Punctual, she listened to all of the instructions I had left for her. Definitely very reliable really appreciated her help and she kept us informed.”
I spent my freshmen and Sophomore year (2[removed]) at college working with preschool English language learners. From 2015 to 2018 I worked at Green Tree Early Education center in Downtown Seattle. After graduating from the University of Washington with a degree in Early Education, I went for a Masters in Computer Science from Northeastern University. During my corporate career, I worked EST which allowed me to be an afterschool nanny/manny starting during the pandemic. I have worked with 7 different families and my undergraduate education was focused on infants and toddlers. Most of my experience is in transitional care / mothers helper while the families are on a waitlist for childcare centers. However my most recent experience was as a nanny/manny for two boys with Autism Spectrum disorder. I have an outdated first aid and CPR certification but I am almost certain there has not been any significant changes since 2017. I am comfortable around pets
“My kids enjoy hanging out with Brian, he is professional and communicates promptly.”
My name is Miley and I have 9 years of experience working with children in a variety of different settings including traditional daycare, Montessori school, nannying, residential, and after school care settings. I have experience with all age groups aged 0-17, however most of my experience has been with young children ages 0-3. I graduated in December 2025 from Portland State with a bachelors degree in psychology, and am currently attending graduate school at the University of Washington for applied child and adolescent psychology. Right now I’m mostly looking for date night type of gigs while I’m in grad school.
Hello! My name is Victoria. I am a certified elementary teacher with a Masters in Teaching from Seattle University. I have many years of experience working with children ages infant to 5th grade. I am flexible and easy-going. I have Montessori experience and I like to let the children lead the activities with me giving structure and guidance.
“Victoria was wonderful. Our kids loved her and were very sad when she had to go! We’re looking forward to our next babysitting opportunity with her.”

"UrbanSitter is my go-to for quality sitters! I can book weeks ahead of time or easily find a same-day sitter when in a bind. I even hired a part-time nanny during a daycare transition. Customer service is helpful and babysitters respond in a timely manner."
