Booked by 7 families in Mercer Island, WA

My name is Butsara, but you can call me Ping. I have over 9 years of childcare experience, including 2 years as an Au Pair and over 7 years working as a nanny. I also worked with one family for over 4 years, helping care for their children as they grew. I hold a Bachelor’s degree in Education and previously taught middle and high school students in Thailand. I also have experience as a private tutor. I’m patient, reliable, and truly enjoy working with children of different ages. For babies and toddlers, I love engaging them through reading, sensory play, music, outdoor walks, and age-appropriate developmental activities. I am CPR & First Aid certified, fully vaccinated, a non-smoker, and comfortable with pets. I look forward to hearing from you Best regards, Butsara

Booked by 1 family in Mercer Island, WA

Hello! My name is Alyssa, I love kids and animals, and am a mother to two beautiful kids, and one handsome cat. I understand how difficult it is to coordinate schedules and find care for the ones who need us most; you need something that not only fits your budget, but also care that meets the level of attentiveness and thoughtfulness that your kids and fur-babies deserve! If you are not happy with public childcare or kennels with large class sizes (or, for those utilizing animal care, cages; ew) and the hefty price for subpar conditions, I get it! You want care that feels like home, feels like family, and takes into consideration the enrichment aspect of your loved one's day. I strive to encourage a growth mindset, connect with nature/get sunshine and fresh air, establish healthy habits, and promote critical thinking in children. For pets, I lead with a warm disposition and exercise gentle yet firm assertiveness where necessary, and genuinely enjoy hanging out with animals; most experience with dogs and cats, but am open to other animals with detailed directions. I am punctual, personable, and remain flexible and graceful under changing conditions. I am a good choice for those who need last-minute care, care during vacations or emergencies, care that fills the gaps between work and school (including transportation), or care on an occasional/semi-regular basis. I do strive to incorporate ways to provide enrichment, learning, and engaging activities as someone who personally has seen and benefited from allowing my own kids to participate in classes, co-ops, and homeschooling. As someone who also felt the same growing pains through motherhood of coordinating schedules, finances, and proper nurturing for my loved ones, I want to be a solution for other families who face the same pressures.

“Alyssa is great. My kids instantly took to her, which I was happily surprised by She is great at managing my fresh walker and my toddlers needs. She is also great at keeping my kids away from me when I am working from home. Finally, she doesn't mind the constant outdoor time my kids demand. ”

Hey there! I’m Dani. I have experience taking care of children of all ages, which has made me know different stages of their development. During a volunteering at a school, I helped children with their academic activities and organizing sports activities, there I learned to combine education with play. Also, as part of my university internship, I worked with children in vulnerable situations, which made me see the importance of creating a safe and enriching environment for them. I love sports, physical activity and crafts, and there is nothing more fun than sharing these activities with children, helping them develop motor skills, creativity and self-confidence. I will be happy to share this time adapted to the needs and personalities of each child. For this reason, I appreciate that as parents you guide me and we have good communication to know the limits and rules you have with them. I hope to meet you soon!

"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)."
