Booked by 3 families in Mercer Island, WA

Hi! My name is Nimco, and I’m a friendly, reliable, and caring person who truly enjoys helping others. As the oldest daughter in my family, I’ve had years of volunteering at a daycare for a year also I have experience caring for my four younger siblings and supporting my family with everyday tasks. I’m great with kids and love spending time with them—whether it’s helping with homework, playing games, or just being someone they can trust and have fun with. I’m always willing to help and bring a positive attitude to any situation. I work well with families, and my goal is to make life easier and more enjoyable for everyone around me.

Booked by 3 families in Mercer Island, WA

OOH TOODLES!! Hello there, I am a local childcare provider with a TON of child care experience. Over the last 13 years I have gained childcare experience ranging from fostering infants to tutoring elementary students, being a nanny, baby sitting, and various other childcare positions (a majority of my experience is with 0-4 years). In my spare time I enjoy traveling, self educating on foreign languages and countries, and creating memories. It is ideal for me to establish with a family who is seeking long term childcare. I am willing to vacation with the family as well as drop off/pick up if age appropriate. I am experienced with light house work for child as well as meal prep and pet friendly. CPR, First aid, blood borne pathogen certified, Valid Driver's license, continuing Early childhood Education credits, experience with sleep training. Availability: Full time shifts Monday - Friday starting as early as 5:00 am ending no later then 5:00 pm (No more then 10 OT hours)

We had a really positive experience with Princess! She helped us out in when we were in a bind with our approaching 5 & 2 year old kiddos. She brings a very calm & positive energy. She came prepared with bubbles and other fun activities for them but asked me what I was okay with before doing anything She kept the kids active and outdoors most of the day which was AMAZING to have them burn off energy. The kids acclimated to her super well & by the time it was time to say goodbye, my son made a comment that he wished she could stay forever (which is not something he’s ever said to any prior sitters we’ve had) She was punctual, and seems to genuinely love children; which our family could feel Look forward to having her back!

Isabella 1 review
$20 per hour for 1 child
Booked by 2 families in Mercer Island, WA

Hi families! My name is Isabella and I have experience working with children here in the U.S. through the Au Pair program, where I cared for kids of different ages, from toddlers to school-aged children. That experience helped me learn how to adapt to different routines, handle responsibilities, and connect with kids in a positive way. I enjoy spending time with children because every day is different — whether it’s helping with homework, reading stories, playing outside, or keeping them entertained with simple activities. I like to create a safe and caring environment while also making sure kids are having fun. I am bilingual (English/Spanish), responsible, and easygoing. Families who have worked with me usually describe me as patient and trustworthy. I’m happy to support with light household tasks related to the kids if needed, and I’m flexible when it comes to schedules. I look forward to meeting new families and being a reliable extra hand when you need one!

I found Isabella on a short late notice, and she was able to accommodate me, she’s very Punctual , very communicative, and took care of my daughter, like if it was me. I appreciate it her so much. I would definitely recommend.

"We absolutely LOVE Isa — our family was so fortunate to have found her through UrbanSitter. I'm a first-time mom, and it took me a long time to find a full-time nanny I could trust to care for our sweet infant boy. Our boy connected with her immediately, and we couldn't have asked for anyone else to care for him. Her calming presence was also perfect for parents like us who work from home. We feel so lucky UrbanSitter helped us find someone who has truly become a part of our family."

"I was so stressed about finding a part-time nanny for my 14-month-old son, who has moderate separation anxiety and hadn't been left with anyone but family before, but we were both immediately at ease in Buhay's presence. Her empathy and commitment to understanding child development are apparent in every interaction I've witnessed between her and my toddler. I feel very lucky to have found her."

"Erna watched our now 5 year old daughter and 3 year old son for a few years. She is punctual, responsible, honest, and playful. What we appreciated most was that she was thoughtful in ensuring that we had a little break; for example, when the kids were clingy, she was able to divert their attention with games or songs or walks to the park. We felt very comfortable leaving our kids with Erna because of her caring nature and experience that spans a decade (including being a live-in nanny)."
