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.

“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! ”

Esmé 3 reviews
$40 per hour for 1 child
Booked by 2 families in Mercer Island, WA

Hi! I’m Esmé, a certified postpartum and infant care doula with over ten years of experience in childcare, including four years working in a daycare setting. Growing up in a large family with more than 40 cousins, I was often surrounded by babies and young children, an environment that provided the foundation for both my confidence and knowledge on caring for little ones. Through years of hands-on experience with countless families, I’ve gained a wide range of practical knowledge, tips, and tools to support parents and kids. Being constantly immersed in communities of parents and children has shown me how essential strong, compassionate support is when raising a child. I would love to become part of your support system and to care for you and your family every step of the way. I offer both daytime and overnight support to best meet your family’s needs.

"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."
