I have about 5 years of childcare experience with children ranging from 5 months to 12 years old. I’ve worked as a babysitter/nanny and in a daycare setting, caring for infants, toddlers, and school-aged children. I enjoy doing crafts, sensory activities, and outdoor activities with children, while also helping with meals and daily routines. I’m fluent in both English and Spanish and can communicate comfortably with children and families in either language. I’m CPR and First Aid certified, have reliable transportation, and have also completed a Medical Assistant program, giving me additional training in safety and caregiving.
Hi! My name is Shamsa, and I am a childcare professional with over four years of experience working with infants and young children in licensed childcare settings, Bright Horizons. I bring a strong foundation in child development, structured routines, and creating calm, engaging environments where children feel safe and supported. I transitioned into nannying to provide individualized, development-focused care. I take an intentional approach by observing each child's needs, thoughtfully adjusting their environment, and creating meaningful, play-based experiences that support growth, independence, and confidence. I have experience in inclusive settings, including supporting children on the autism spectrum. I provide consistent, detailed updates so families feel informed, reassured, and connected throughout the day. I am CPR and First Aid certified, reliable, and available am fully vaccinated. (Dedicated to providing consistent, reliable care families can depend on.)
Hi all! My name is Margaret (she/her) and I am, by day, a private practice somatic therapist. I received a BS in Psychology and Family Science and minor in Women's Studies. I received my masters in Social Work from UW. I love working with adults & being in the body, but deeply miss the childcare that I was doing before my career. I have around ~15 years of babysitting experience with kids ranged from 9 months - 14 years old. I love the energy kids have and so appreciate their awe and excitement about the world. I value encouragement, curiosity, creativity, communication, autonomy, and mindfulness in my interactions with kids! I strive to be a thoughtful and caring companion and role model, not a detached authoritative figure. I value boundaries and helping kids learn how to hear and say no, along with trusting their own boundaries and choices. Ultimately, I enjoy being in the fluidity of being with kids - I love making art, singing, dancing, being silly with kids; doing the mundane things such as helping structure chores; engaging in emotionally challenging situations and helping build self-assuredness in feeling through emotions. I highly value relational building with kids and their families and appreciate transparent communication, collaboration, trust, accountability, and overall co-creating safety for your child/ren. I would love to chat more with you and your family to see if this would be a good fit for you all.
✨ 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.

"Caitlin was awesome and jumped right in to chaperone four girls (10, 9, 8 and 6) at a family wedding (they were bridesmaids) and she was very helpful with the event as well as taking them home and putting them to bed."

"McKenna was great with our 3 year old son! She came prepared with a box of fun activities and handled playing, dinner, and bedtime seamlessly... and it was all at our hotel while we were in town for a wedding. Thank you McKenna!"
