Booked by 19 families in Mercer Island, WA

Hi, my name is Diana! I’m 30 years old and hold a bachelor’s degree in Educational Psychology. I’m currently working as an early preschool teacher, and I’m passionate about children’s development and the many ways they learn. I love exploring how kids think, feel, express themselves, and how to best support their growth. I have over 10 years of experience caring for children—as both a nanny and during my college years. I’ve also worked as a Spanish and English teacher, as well as with larger groups of children, so I feel confident creating engaging activities for all ages. Some of my favorite things to do with kids include crafts, painting, science experiments, puzzles, board games, and outdoor sports. I also enjoy helping with homework, teaching Spanish, encouraging positive behavior, and offering light household support. I’m fully vaccinated and certified in CPR, First Aid, and MERIT by Early Learning Professionals in Washington. I’d love to bring creativity, patience, and fun into your child’s day while making sure they feel safe and supported.

“Diana was our son's nanny for a year and she was the best! Always arrived on time, quick to learn our routine, knew what to do with little instruction, was a self-starter. We trusted our son with her and let her lead with which activities to do at home. She was pretty much the perfect nanny for us. We definitely recommend her.”

Booked by 12 families in Mercer Island, WA

Hi there! My name is Allison and I’m 29 with about 15 years of childcare experience spanning all ages. I’m a recent transplant to Seattle - originally from Chicago, but spent the last three years living on the Big Island of Hawaii. I usually work full time in marketing, but right now am on the hunt for my next role - which opens up my daytime availability for childcare! I’ve worked with countless families, from nannying for vacationing families in Hawaii to spending 5 years with a Chicago family as their several times a week babysitter. I love to read, travel, and hike - please let me know if you’d like to chat further!

“Easy going, playful and engaged effortlessly with my 6/4 year olds. Highly recommend. ”

Booked by 8 families in Mercer Island, WA

Hi! 🌟 My name is Gabriela and I have over 8 years of experience working with children, always with love, responsibility, and dedication. I’m currently looking for a part-time position, ideally 4–5 hours a day, Monday through Friday, as I’m growing my own small business and looking for a schedule that allows me to balance both. My ideal hours would be 9:00 AM–1:00 PM or 8:00 AM–12:00 PM/1:00 PM, but I’m flexible. I truly enjoy organizing and creating calm, functional spaces, so I’d be happy to work as a Mother’s Helper, helping with household organization, laundry, tidying up, meal prep for the kids, and other light household tasks. I’m also available to help care for children if needed. I have several years of nanny experience and genuinely love working with kids. If you or someone you know is looking for an extra set of hands during the day, I’d love to connect! 📚 Experience with multiple age groups 🗣️ Trilingual: Portuguese | English | Spanish 🫶🏼 Caring, patient, and reliable ✅ References available Thank you 💛

“Gabby is very professional and demonstrated great communication skills throughout the process. Our kids loved having her over. We will definitely reach out to her again the next time we are looking for a sitter and would highly recommend to other parents. ”
