Booked by 2 families in Mercer Island, WA

Hi! My name is Monet. I’m 27 years old and originally from Thailand. I am offering child care, senior care, and household support. I have experience working with children of all ages. I worked as a kindergarten and elementary teacher in Thailand for 4 years, and I have spent the last 2 years as an au pair caring for infants and young children. I especially enjoy cooking, doing arts and crafts, and creating age-appropriate developmental activities. I grew up around pets including dogs, cats, and fish so I am very comfortable working in homes with animals. I have also provided senior care for my own grandparents and can assist with cooking, light cleaning, driving to appointments, and daily tasks. I am reliable, patient, and committed to creating a safe and positive environment for the families I work with.

"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."
