I excel at keeping kids active, helping them navigate complex emotions, and building positive habits through gentle but firm boundaries. - Active & Outdoor Fun: I love nature walks and am always excited to take older kids hiking! I thrive on keeping children engaged with the outdoors, exploring local trails, and staying active in a fun, safe environment. - Bonus for Pet Owners: I am an animal lover!

Julisa $23 per hour for 1 child

Hi! I’m Julisa, a senior at the University of Washington offering dependable child care, pet care, and light household support in the Seattle area. I’ve cared for children ages 6 months to early teens since I was 16, bringing a mix of energy, patience, and creativity to each job—whether it’s playtime, homework help, or school pickups. I have a safe, reliable car and am comfortable driving kids to activities, appointments, or wherever they need to go. I’m a lifelong animal lover with experience caring for both dogs and cats. I’ve worked with reactive dogs and have hands-on experience with puppy training as well. I grew up with two cats and now have a dog named Orion, who’s back home in California with my family. Alongside child and pet care, I’m happy to help with light cooking, tidying up, errands, or anything else that keeps your home running smoothly.

Marcela $30 per hour for 1 child

Hello, parents!! My name is Marcela — or as the little ones call me, Cela :) I studied psychology in Brazil and spent five years immersed in childcare there before moving to the US, and for almost three years now I've had the joy of caring for two wonderful local families, watching their babies grow from tiny newborns into happy, curious toddlers. I love imaginative play, art and crafts and exploring the world w/ the little ones - parks, libraries, story times. I'm patient, attentive, and genuinely present. I'm a non-smoker, non-drinker, comfortable driving and happy to share references from the families I currently work with. I'd love the chance to meet you and your kiddo! 💛

"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!"
