"Amina came and helped us out when our babysitter canceled last minute. She was great with our kids. Even our 11 month old son who has stranger anxiety warmed up to her."

Booked by 1 family in Mercer Island, WA
Hi there! My name is Natalie and I was a babysitter in high school for 3 years. I babysat a little boy from age 2-5 years old over the course of high school. After graduating from Holy Names Academy, I finished my bachelors degree at Bellevue College. I currently work at a real estate office and would love the opportunity to nanny on the weekends and Friday nights! I love children and really enjoy being a reliable resource for families who are looking for childcare. If you have any questions or want to learn more about me, please feel free to reach out!
“Natalie is the best! My 2 little boys loved spending NYE with Natalie. She made the night so fun for them with smores and celebrations. I highly recommend! My boys keep asking when she can come over again. Thanks Natalie!!”
Lily $32 per hour for 1 child
Hi! I would say that I'm a dependable and caring caregiver with 6 years of nanny experience along with 2 years working in a daycare setting. I've cared for children of various ages, especially infants and toddlers, and I'm very comfortable with feeding routines, diaper changes, nap schedules, and creating a safe, nurturing environment. My daycare experience has also helped me develop strong skills in managing multiple children, staying organized, and keeping kids engaged through age-appropriate activities. I'm patient, attentive, and genuinely enjoy building positive connections with the families I work with. I understand how important trust and communication are, and I always aim to provide reliable, consistent care that gives parents peace of mind. I'd love the opportunity to connect and see if I'd be a good fit for your family!
Anthea $25 per hour for 1 child
I LOVE being with children! Growing up in a huge family, I've always been surrounded by kids, so it's been a pretty easy task to take care of them. I started babysitting when I was 11, and then gradually it turned into a regular thing. I have been a part-time nanny, and now that I'm a full time Esthetician, I pick up babysitting shifts and date nights regularly! I baby-sit at least three times a month. I have watched children from the ages of new born to 11 years of age.
