Naomi $25 per hour for 1 child
Booked by 1 family in Mercer Island, WA

Hi my name is Naomi and I'm new to the Seattle area ! Originally from Spokane, I'm the middle child of 9 siblings, so I'm all too familiar with raising, watching, and caring for kids. There's nothing like the joy that children give and I am so eager to be a part of a family, since I sadly moved away for mine to pursue my career. I am a DJ and have DJed for about 5 years now doing a variety of different events. This profession keeps my days completely open and are waiting to be filled up ! I played college basketball and sports have always been an integral part of my life, I love to play, read, and learn; and indulge in anything creative. Whether it's music, drawing, painting, photography or fashion, my gravitation to the arts remains in my admiration for art and beauty in general. My goal for your children is to enhance their love for life and appreciation for what's around them through organic human interaction and care.

Aicha $25 per hour for 1 child

Hi! My name is Aicha, and I’m a caring, responsible babysitter with hands-on experience taking care of children. I’m the oldest sibling in my family, and I’ve spent many years helping care for my two younger sisters, especially my youngest sister, who I’ve helped look after for most of her life. Because of this, I’m very comfortable with kids and understand the importance of patience, routines, and keeping children safe and comfortable. I’ve helped with meals, homework, bedtime routines, and keeping kids entertained in a positive way. I’m calm, attentive, and always make sure kids feel cared for and supported. I take responsibility seriously and know how important trust is when it comes to childcare. I’m dependable, respectful, and easy to communicate with. I’m also happy to help with light cleaning or tidying up after the kids if needed.

$25 per hour for 1 child
Booked by 1 family in Mercer Island, WA

Hello! I am a daycare teacher at a big chain daycare. I typically work with infants but also work with kids up to age 6. I have all my childcare trainings completed, including CPR, 30hr child care basics, WA Initial certificate, food workers permit and more. I am also a mom of 2 girls (4 and 2yrs).

“We had a wonderful experience with Teresa! She did an incredible job taking care of our baby and handled all the feedings and diaper changes with total ease. You can really tell they have a wealth of experience from their time working at a daycare. On top of being highly capable and attentive, they were perfectly punctual and so incredibly friendly. We felt completely comfortable leaving our little one in their care and would highly recommend them to any family!”

"Johanna is AMAZING! My two boys love her - she does everything from amazing arts & crafts, to helping with homework, to getting them playing outside! She also drives them and does everything involved with after school activities: packing snacks, getting the right gear, etc."

"When we hired Amani, we felt like we hit the jackpot. We were very lucky to find her on UrbanSitter at the beginning of school year. She was picking up kids from school, taking them to afternoon activities, helping them with assignments. She prepped food for them, helped organize their closets and keep their spaces neat and orderly. We would hire her again in a heartbeat."

"Caitlin has been such a lifesaver for our family. We hired Caitlin to help with the after school routine. The kids took to her instantly. She does it all - school pick ups, dinners, baths, lunch making, clean up, etc. She has really helped make a busy time so much easier for us."
