Selah $35 per hour for 1 child

Hi! I’m 22 years old and was born and raised in the central Seattle area. I’ve been working in childcare for the past four years, and it’s truly something I care deeply about. Supporting children as they learn, grow, and develop their own unique personalities is incredibly rewarding to me. My passion has always been caring for children, and I strive to create a safe, nurturing, and engaging environment where they feel comfortable and valued. I love building meaningful connections not only with the kids I care for, but also with their families. I’m excited for the opportunity to get to know you and your family, and I look forward to becoming a trusted and positive part of your lives.

Margaret $50 per hour for 1 child

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.

Hi families! Looking for a warm and present nanny? I have a passion for working with children and helping them learn and grow. My 5+ years of experience—including working in daycares, summer camps, babysitting, and nannying for an amazing family over the past 2 years—have prepared me to provide safe, reliable, and engaging childcare. As a patient, calm, and creative caregiver, I prioritize open communication with parents to ensure their peace of mind, and I follow their lead when it comes to enforcing household rules. My priority is your children and creating an environment where they can grow and families feel supported. I look forward to getting to know you!

I have 10 years of experience working with families taking care of their kids. I’ve been working as a full time nanny and as a part time teacher. I have a BLS, CPR certification, I am fully COVID vaccinated, all the vaccines up to date such as MMR, HepB, Flu shot and more. I have my own car available to use with your kids, clean driving record, and exceptional driving skills. I enjoy being able to help in the developmental process of each child. I have been using development tools for years such as Kinedu and Baby-Led Weaning. Apps designed to support parents in nurturing their child's development through play as well providing foods that are nutritious for babies in a way that they can handle them. I’m bilingual, English-Spanish and I enjoy teaching these languages through reading, singing, play time and throughout their daily’s routine. I’m a sporting person, I like swimming, gymnastics and I workout regularly to keep myself healthy. I have experience taking the kids to swimming classes, gymnastics, and outdoors- indoors activities. I’m a Montessori fan and I’m happy to share my knowledge and experience to help your kids in a fun way to use it, love it and apply it in their lives as in their playrooms, bedrooms, pantries, meal times, hygiene routines, schooling activities and more. I’m a tidy person so I love helping out families at home. My background is in child development as well in nursing. I’m currently a CNA. I have great references from the families I’ve worked for and I’ll be happy to share them with you. Feel free to reach out to me, I’d love to get to know your family, share smiles with your little ones and be helpful in anything that you’ll need.

"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!"
