Angela $22 per hour for 1 child

I’m looking to pick up some part-time evening and weekend babysitting in the West Seattle/White Center area. A little about me: • I’m currently an addiction counselor working in the ER in social services (Mon–Fri) • Over 10 years of experience working with children, teens, and adults (ages 9–80) • Licensed through the WA Department of Health • Experienced with kids of all ages—from helping raise my younger siblings to parenting my own teen I’m reliable, calm, and genuinely enjoy spending time with kids—whether that’s playing, helping with homework, or keeping routines consistent with your parenting style. I take safety and professionalism seriously, both on and off the job. Because I work in healthcare, I’ve consistently had Adult, Child, and Infant CPR/First Aid/AED. I graduated with a bachelor’s in behavioral science (close to social work) 6/2025. Starting this fall, I’ll be attending UW for my MSW, and I’m looking to earn some extra income doing something I enjoy. If you or someone you know is looking for occasional or regular childcare, feel free to message me!

Ella $24 per hour for 1 child

Hello! My name is Ella and I am a recent college graduate interested in working with kids! I love babysitting toddlers and kids -- I have previously wrangled little ones moving through summer theatre and dance camps, and I have special skills in working with easily distracted kids and getting them back on track :) I am also available to catsit, dogsit, and housesit upon request!

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! 💛

Booked by 1 family in Mercer Island, WA

Hello! My name is Katie. I have been working as a full time nanny for the last 6 years, and babysat for several years prior as well. I have cared for kids aged 4 months to 10 years, and also helped as a household manager- scheduling appointments and running errands. Additionally, I have experience working in a Montessori school/daycare. I would love to chat more and see if I could be a good fit with your family!

Booked by 1 family in Mercer Island, WA

Hi - I’m Joey - I'm 61 and full of energy! I am offering child care and household services. Also- special event services/catering, party help. I'm semi-retired, after some amazing careers (from clothing design, baby boutique owner, event planning to catering)- and now I'm focusing on my art and working part time at a few of my interests. I spend a lot of time in nature walking and hiking with my dog Blue- rain or shine. (Also, spend a lot of time at Pickleball!) I love babies and kids- I'm a very patient, helpful, friendly person and love meeting new people. My adult daughters always tell me that I should be a caregiver/babysitter/nanny. I'm happy to help with homework, reading, doing crafts, going for walks etc. My baby/child care started very early- When I was 10 my mom had #5 and basically handed her over. We are very close now still. I can cook, clean, drive to appointments, or do other tasks. I have helped my 81 year mother quite a bit and am comfortable with senior care. I have always had dogs and cats and am happy to take care of those as well! I have current CPR and First Aid certificates. Love to meet in person! Joey

“Joey helped us out on very short notice. I really appreciated her flexibly, since I hadn't had time to really make plans. She got along great with our toddler and was warm, attentive, and professional.”
