Hey there! I’m Dani. I have experience taking care of children of all ages, which has made me know different stages of their development. During a volunteering at a school, I helped children with their academic activities and organizing sports activities, there I learned to combine education with play. Also, as part of my university internship, I worked with children in vulnerable situations, which made me see the importance of creating a safe and enriching environment for them. I love sports, physical activity and crafts, and there is nothing more fun than sharing these activities with children, helping them develop motor skills, creativity and self-confidence. I will be happy to share this time adapted to the needs and personalities of each child. For this reason, I appreciate that as parents you guide me and we have good communication to know the limits and rules you have with them. I hope to meet you soon!

Hello! My name's Emily, and I'm a recent graduate from the University of Washington. I've mainly worked with children in the K-5 age range, but I'm very open to babysitting children of younger ages as well! Most recently, this last summer I was employed as an Assistant Instructor at IslandWood, an environmental education day camp on Bainbridge Island. I've also worked as an After-School Counselor at Wedgwood Elementary School. Additionally, I have past experience as a babysitter with middle-school aged children. I have a Honda CR-V with four seats (three in the back seat, one in the front seat if old enough) if any type of driving is needed. If you would like to talk further or have any questions, feel free to contact me!

FYI I am located in the Fremont area and do not have a car. Only accepting clients in Seattle proper unless transportation is otherwise coordinated. Thank you! Hi! I’ve been caring for kids, pets, and helping households in different ways for many years. I started babysitting in high school and continued on and off through college, and also worked as a camp counselor in high school with kids going into kindergarten. I’m additionally a proud aunt to two boys (Ian is 3, and Ellis was just born on May 2!) and have spent a lot of time caring for and babysitting them over the years. I’m naturally very creative, patient, attentive, and emotionally aware, and I care a lot about making sure kids feel safe, listened to, respected, and genuinely seen. I’m also reliable, responsible, and organized, so parents can feel comfortable knowing things will actually be handled well and consistently. I enjoy engaging with kids in a real way rather than just supervising them passively, whether that means creative activities, outdoor time, games, helping with routines, or simply being a calm and supportive presence. Animals have also been a huge part of my life. I grew up with dogs, worked at a dog groomer in high school, fostered dogs through the ASPCA and Furever Home Rescue in New Jersey, and adopted my own rescue dog through Big Dog Rescue Project in 2020. I currently work professionally through Rover and have experience with walks, drop-ins, overnight care, routines, medication support, and caring for pets with different personalities, needs, and energy levels. I take pet care very seriously and understand how important trust, communication, safety, and consistency are when someone is caring for a beloved animal. Beyond caregiving, I’m also highly organized and happy to help with general household support such as tidying, organizing, errands, light cleaning, meal prep, pet-related cleanup, receiving deliveries, watering plants, or helping keep things running smoothly overall. I’m adaptable, detail-oriented, calm under pressure, and genuinely enjoy helping create a more peaceful and supported environment for people. I’m new to Urban Sitter and haven’t collected reviews here yet, but you can find reviews on my Bambino babysitter profile, or check out my LinkedIn page. Happy to provide both to you when we connect.

"Johanna is AMAZING! My two boys love her - she does everything from amazing arts & crafts, to helping with homework, to getting them playing outside! She also drives them and does everything involved with after school activities: packing snacks, getting the right gear, etc."

"When we hired Amani, we felt like we hit the jackpot. We were very lucky to find her on UrbanSitter at the beginning of school year. She was picking up kids from school, taking them to afternoon activities, helping them with assignments. She prepped food for them, helped organize their closets and keep their spaces neat and orderly. We would hire her again in a heartbeat."

"Caitlin has been such a lifesaver for our family. We hired Caitlin to help with the after school routine. The kids took to her instantly. She does it all - school pick ups, dinners, baths, lunch making, clean up, etc. She has really helped make a busy time so much easier for us."
