✨ Hello, nice to meet you ✨ My name is Mabel and I have over 6 years of experience working with children from 2 months to 14 years old. During this time, I’ve had the joy of supporting their growth, guiding their development, and creating a safe and loving environment for them. I consider myself a responsible, kind, and patient person who always strives to ensure children feel cared for, happy, and encouraged at every stage of their lives. I enjoy planning creative, educational, and fun activities that nurture learning while also giving parents peace of mind. For me, being a nanny is not just a job – it’s a true commitment to each family and to the well-being of their little ones. 💛
Hello there! I am Milena, i studied at Bellevue christian school before moving to online and am on a gap year before heading to college! I worked at mercer island elementary as a Teachers assistant where i truly found my love for children. Growing up i was always babysitting and always knew i wanted kids of my own. I enjoy readying, going to the park, and playing with all my nanny kids favorite toys. I would describe myself as loving, communicative, and reliable.
Hi, I’m April and I’m an experienced pediatric RN here to help you find time to recharge while knowing your kiddos are safe, cared for, and having fun! I've worked with children from newborns to young adults as a pediatric and school nurse and babysitter. In addition, I've worked as a community RN supporting families during pregnancy and early childhood. I'm also a parent myself, so I know how much parents need time to themselves *and* how hard it is to trust anyone else with your kids. I'm certified in CPR/BLS and have extensive education in child development, allowing me to meet each child at their level. I prioritize communication and respect with both kids and parents, and I'm always happy to follow your lead. I’m also comfortable caring for pets and providing light housecleaning and meal prep.

A few fun facts about me: I love arts & crafts, hiking, spending time with family, & exploring new restaurants and cafés!

Please feel free to reach out with any questions

"We were incredibly grateful that Maya was able to help us out with a last-minute childcare emergency. She matched our 9-year-old's energy with arts & crafts, some quiet reading, and a walk around the neighborhood. We'd have Maya back in a heartbeat!"
Hillary S., parent
"We used Tania for a last minute emergency. She responded very quickly. My daughter seemed to enjoy herself. My son napped most of the time. I enjoyed how she kept me updated by text."
