Booked by 4 families in Mercer Island, WA

Hi, I’m Cielo Martinez, a Seattle-based caregiver with experience supporting high school students in Seattle Public Schools and caring for little one’s ages newborn to five through home visits through EHS. I’ve also grown up helping raise my nieces and nephews, which taught me a lot about patience and keeping things fun and safe. I like doing arts and crafts, homework help, and outdoor play. I’m comfortable with pets, feeding, walking, playtime, and I have two dogs myself. I speak Spanish and English, and I bring a warm but dependable presence. I’m also babysitting on the side to help save for my future wedding. I’m more than happy to answer any other additional questions you might have!

“Cielo was on time and very responsive. I have two very active boys and she kept them engaged and happy all afternoon. We will definitely hire her again. ”

Booked by 2 families in Mercer Island, WA

My name is Aracely , and I am a 29 year-old dedicated childcare provider from Bolivia. With a strong passion for child development, I have gained valuable experience in childcare, focusing on creating a safe, engaging, and nurturing environment for children. My goal is to support children's growth through creative activities, positive reinforcement, and structured routines that foster learning and emotional well-being. I take pride in building meaningful connections with children and their families, understanding their unique needs, and providing reliable care. My experience working with children of different ages and backgrounds has strengthened my ability to adapt

“Bottom line: Book Aracely without any hesitation! She was amazing with my high-energy 4 yr old son and 'stranger danger'-fearing 7 mo old daughter! For my son, she did arts and crafts projects with him and lots of imaginative play.  She was a natural with my daughter, immediately putting her to ease. After just one comment, she very quickly learned my daughter's routine and put her down for a nap, changed her, and fed her. During my daughter's wake window, Aracely read books and engaged her with toys. I was more comfortable having my kids in Aracely's care after just an hour than some of my past nannies who were with our family for months. She's calm, nurturing, and a wonderful communicator. She radiates warmth and just after she left, my son asked when Ms. Aracely will be back. I'll book her again in a heartbeat... unless another family beats me to it.”

"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."
