Booked by 4 families in Mercer Island, WA

Hi there! I'm Esra - a calm, reliable, and caring nanny who truly loves spending time with little ones. I've worked with infants, toddlers, and young children, including full-time experience with a 6-month-old during my au pair year. I'm patient, safety-focused, and always try to create a warm, happy, and structured environment for kids. • Experience with infants, toddlers, and young children • CPR & First Aid certified • Fully engaged playtime (reading, sensory play, outdoor walks, tummy time, developmental activities) • Ability to follow routines (naps, bottles, meals, bedtime) • Light housekeeping related to the child (dishes, laundry, tidying play areas) • Respectful, kind, and warm presence • Comfortable with pets • Open to trial/meet & greet calls

“We hired Esra to care for our 10-month-old son, and she has been excellent. She is caring, gentle, and patient. She engages with him through play, songs, and outdoor walks, and he enjoys his time with her. We’re grateful for her support.”

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. ”

Hi, I’m Summer! I’m currently a part time nanny for twin 5 year olds and looking to pick up extra hours while I’m on break from school. I study Speech Pathology online and got certified this year to teach kids yoga which I’ve been loving and teach on occasion. I also have experience teaching swim lessons and have several years of childcare experience with kids of all ages, including multiple sets of twins. I’m CPR and First Aid certified and enjoy keeping kids engaged with fun activities that help them learn and grow.

“Summer was fantastic! She was professional, warm and engaging and my 10 year old daughter loved her from the second she walked through the door. Will definitely hire Summer again!”
