Heather $21 per hour for 1 child

With a solid foundation in caregiving, I am a third-year nursing student at Seattle University with plans to specialize in pediatrics due to my passion for working with children. I’ve gained valuable hands-on experience through babysitting kids from 5 months to 12 years old, completing a geriatric clinical, and volunteering at animal shelters. My time in Girl Scouts honed my leadership and caregiving skills, while my love for animals shows through caring for pets like cats, snakes, and even chickens. My rescue dog Mango, who I’ve had since childhood, reflects my lifelong commitment to care and compassion. Additionally, I have a passion for cooking, particularly baking, which I love to share with the families I work with, creating fun and delicious treats.

Ellen $20 per hour for 1 child

Hi! My name is Anders, and I’m a passionate, reliable caregiver with a background in child development and creative enrichment. I hold a B.A. in Psychology from the University of Washington, where I focused my studies on child development. I have been a full-time nanny and currently help run an arts-based after-school program in North Seattle that supports kids with intellectual and developmental disabilities, as well as those navigating complex home situations. In addition to that work, I volunteer each summer as a camp counselor at Camp Erin, a bereavement camp for children and teens. Through these experiences, I’ve gained deep insight into supporting kids and teens as they process big emotions with compassion and care. I'm especially committed to creating inclusive, affirming environments for children of all identities and abilities. I’ve worked as a full-time nanny and have been babysitting for families for the past 15 years. I love incorporating engaging arts and crafts projects, Cooking projects, and imaginative play into my time with kids—activities that spark creativity and confidence. I bring warmth, patience, and a calm presence to every home I work in, and I always strive to meet kids where they are with kindness and respect. I look forward to connecting with a family that values a thoughtful, nurturing caregiver who encourages kids to explore, express, and get imaginative!

Additional experience with children includes working as a child care assistant at a daycare, helping families and children have a fun and safe time on attractions at Walt Disney World while working as a Disney college program intern, and volunteering as a camp counselor at a camp for children battling life threatening or disabling medical conditions.
