Hello, I'm Fatuma, a student with a passion for working with children. In 2023, I worked as a camp aide teacher at the Pacific Science Center. Due to my religion, I cannot work with dogs; but willing to work with any other animals.I am capable of handling housework and running nearby errands. I've completed a first aid class, holding a valid certificate, and plan to retake the course for a refresher soon. Seeing the kids I work with grow and show their personality is the reason why I love being a babysitter/nanny. I enjoy reading, cooking and baking, going to the park, watching movies, going out to have fun, etc.

Available evenings, overnights, and last-minute requests, every day after 5:00 PM Hi there! I'm a Seattle-based college student in my final year, living in Bellevue looking for evening and overnight babysitting opportunities. Experience: - 9+ years of childcare experience, starting with my niece at age 1 (she's 10 now!) - Long-term care for two brothers, watched since they were 2 and 4 (now 5 and 7) - Cared for two professors' families, with kids ages 2-4, including managing two children at once - Comfortable with kids ages 1 and above individually or in groups Pet-Friendly: Grew up with two dogs and I'm comfortable around dogs, cats, fish, turtles, and parrots - your furry (or scaly!) family members are in good hands too. Beyond Childcare: I'm happy to help with light housework while I'm there - things like tidying up toys and play areas, washing bottles or dishes, folding laundry, or wiping down kitchen surfaces. I like leaving things a little tidier than I found them so you come home to one less thing on your plate. :) What I Offer - Reliable, patient, and genuinely enjoy spending time with kids - Homework help, bedtime routines, and keeping things fun and calm - Comfortable pitching in with light chores when needed - Flexible for last-minute and overnight requests Feel free to reach out anytime to chat more or set up a meet-and-greet! :)

Hey there, I’m Julia – Ready to make your home life a little smoother. Hi, I’m 28 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.

"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."
