Booked by 127 families in Mercer Island, WA

Hello! I have a full time job so at this time I am not accepting bookings from new families during M-F at this time. My name is Jasmine! I’m a Seattle native and a dedicated and experienced nanny with over 6 years of experience in providing exceptional care for children of all ages. I’m passionate about creating a nurturing and stimulating environment for children of all ages! My approach to childcare is rooted in a strong commitment to safety, education, and emotional support. I believe in fostering a positive and fun atmosphere while also encouraging development through age appropriate activities. Whether it’s helping with homework, organizing creative play, or managing daily routines, I strive to be a reliable and supportive presence in every child’s life. I’m also skilled in handling various aspects of household management, including meal preparation, light housekeeping, and scheduling. My goal is to ensure that parents feel confident and at ease knowing their children are in capable hands. Please feel free to reach out anytime if you have any questions or want to know more! I look forward to speaking with you! Thank you so much!

“Jasmine has helped us out a few times with our 4 and 1 year old! She was very sweet and attentive. Our kiddos warmed up to her with ease! Would recommend and have her back, and intend to! ”

Hi. My name is Itu. I’m a very dependable babysitter, who knows how to provide exceptional care for your children. I have 8 years experience with children of all ages starting from infants to teenagers. I’m well-versed in creating a fun, nurturing environment that kids love and parents trust. I’m CPR and First Aid Certified. And also as all families are unique, I don’t really have a specific way of how I do things, you tell me what you need and I do just that, adding a little bit where I think it’s needed but otherwise I tailor my approach to fit your child’s needs and your household routines.. I’m dedicated to making babysitting time special for your children and stress-free for you. Thank you! Chat to you soon..

Booked by 12 families in Mercer Island, WA

Hi there! My name is Allison and I’m 29 with about 15 years of childcare experience spanning all ages. I’m a recent transplant to Seattle - originally from Chicago, but spent the last three years living on the Big Island of Hawaii. I usually work full time in marketing, but right now am on the hunt for my next role - which opens up my daytime availability for childcare! I’ve worked with countless families, from nannying for vacationing families in Hawaii to spending 5 years with a Chicago family as their several times a week babysitter. I love to read, travel, and hike - please let me know if you’d like to chat further!

“Easy going, playful and engaged effortlessly with my 6/4 year olds. Highly recommend. ”
