Booked by 38 families in Mercer Island, WA

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.

Right on time, connected right away with my 9 yo son who is restricted to bed due to Long Covid, so grumpy. She made him happy playing games with him so he didn’t feel trapped and bored. He really liked her

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.

Hello, my name is Alannah. I am currently toddler/all school support teacher at Primrose School. I am very dedicated to making sure the children’s needs are always first! I have been in childcare for around 7 years now. I started as a tutor then worked my way to becoming a babysitter. I enjoy learning while we play, and I would love to help out in anyway I can. I have all my childcare trainings with background checks and I’m currently in college earning my bachelor’s degree in secondary education. I have 2 dogs so I have no problem taking care of pets. I love learning so if there is anything that I do not know, I will always love to learn about it.

"We absolutely LOVE Isa — our family was so fortunate to have found her through UrbanSitter. I'm a first-time mom, and it took me a long time to find a full-time nanny I could trust to care for our sweet infant boy. Our boy connected with her immediately, and we couldn't have asked for anyone else to care for him. Her calming presence was also perfect for parents like us who work from home. We feel so lucky UrbanSitter helped us find someone who has truly become a part of our family."

"I was so stressed about finding a part-time nanny for my 14-month-old son, who has moderate separation anxiety and hadn't been left with anyone but family before, but we were both immediately at ease in Buhay's presence. Her empathy and commitment to understanding child development are apparent in every interaction I've witnessed between her and my toddler. I feel very lucky to have found her."

Kamilah W., mom of one

photo of quoted parent Eric

"Erna watched our now 5 year old daughter and 3 year old son for a few years. She is punctual, responsible, honest, and playful. What we appreciated most was that she was thoughtful in ensuring that we had a little break; for example, when the kids were clingy, she was able to divert their attention with games or songs or walks to the park. We felt very comfortable leaving our kids with Erna because of her caring nature and experience that spans a decade (including being a live-in nanny)."

Eric D., dad of two
