Booked by 19 families in Mercer Island, WA

Hi, my name is Diana! I’m 30 years old and hold a bachelor’s degree in Educational Psychology. I’m currently working as an early preschool teacher, and I’m passionate about children’s development and the many ways they learn. I love exploring how kids think, feel, express themselves, and how to best support their growth. I have over 10 years of experience caring for children—as both a nanny and during my college years. I’ve also worked as a Spanish and English teacher, as well as with larger groups of children, so I feel confident creating engaging activities for all ages. Some of my favorite things to do with kids include crafts, painting, science experiments, puzzles, board games, and outdoor sports. I also enjoy helping with homework, teaching Spanish, encouraging positive behavior, and offering light household support. I’m fully vaccinated and certified in CPR, First Aid, and MERIT by Early Learning Professionals in Washington. I’d love to bring creativity, patience, and fun into your child’s day while making sure they feel safe and supported.

Diana was our son's nanny for a year and she was the best! Always arrived on time, quick to learn our routine, knew what to do with little instruction, was a self-starter. We trusted our son with her and let her lead with which activities to do at home. She was pretty much the perfect nanny for us. We definitely recommend her.

Hi my name is Paula I am an Irish Primary school teacher (elementary teacher) I have my Honors Bachleors Degree in Early Childcare and Education where I’m an Early childcare practitioner along with my Masters of Education where I have been Primary teaching (Elementary and Middle school) for the last 5 years in Ireland I absolutely love what I do. I was also a preschool (daycare) and after school teacher for 2 years in Ireland before I became a Primary Teacher. I have years of experience working with all age groups of children I love what I do, my favourite things to do are singing, acting, music,and art with the children, go for walks to the park, creativity is so important for little ones to learn and develop. I have my child care protection and CPR certificates both from Ireland and from America and my garda vetting. In January 2012 I moved to San Francisco where I had the pleasure to be a nanny for 2 and half year old twins for a beautiful family from 2012 to 2013 then I was a full time nanny working with another amazing family and three beautiful children from December 2012 until August 2015 during this time at weekends I would also do some babysitting on ‘Urbansitter’ and I loved the families I got to know through this app. Then at the end of August I decided to move home and become a teacher. I now have moved to Seattle with my husband and I am hoping to find some babysitting work here and teach also. My past experience consists of fundraising for children in South Africa. I did volunteer work in August, 2009 and setup fundraisers and raised 6,000 Euros for the children. If you would like to know more about me message me, thanks for reading this Paula. Unfortunately I am very allergic to hair on animals so I cant be around dogs and cats in the same room which is really unfortunate as I love animals too.

Paula helped us out when we had a last minute need - she was terrific and put my mind at ease immediately. Patient, caring and a lot of fun, our one year old had a great day with Paula - she even sent us photos throughout the day. Would highly recommend!

Booked by 18 families in Mercer Island, WA

Hi! I’m Katie and I’ve been caring for children for 15+ years. I am passionate about the nurturing and education of children, and enjoy fostering their individual growth and development. I recently graduated from the University of Washington with a Bachelor of Science in Geoscience and a Minor in Disability Studies. My future goal is to merge my love for childcare, pedagogy, disability studies and environmental science into a learning center for kids. I have extensive experience with children of all ages, from infants to teenagers. Starting my childcare career as a teenager myself, I have continuously improved my skills through hands-on experience, training courses, certifications, and educational coursework over the past 15 years. Alongside providing in-home care, I have also gained valuable experience working in educational and recreational settings. I am passionate about creating inclusive and supportive environments that empower children to thrive and succeed. I use adaptive caregiving techniques to meet the individual needs of children with diverse abilities. Through a blend of educational, professional, and personal experiences, I have honed my skills in customizing activities, environments and curriculum to best suit various learning styles, disabilities and abilities. My favorite activity to do with kids is exploring and playing outdoors in nature. I also love engaging in games, arts and crafts, science experiments, cooking and baking, reading, music, and dance, among other activities! One of my go-to activities, with parental permission, for first visits is making homemade play-dough. It's a simple yet fun activity to break the ice and allow the kids and me to get to know each other. Extra info: In addition to childcare, I’m available to help with tutoring, homework, preparing meals, light cleaning, and errands. I’m an animal lover so any pets are fine by me. In addition to lots of pets and play I’m happy to help with feeding, walks, etc.

Katie was prompt, communicative, flexible, kind, and great with our kids. We would definitely hire her again!

"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."

Kamilah W., mom of one

photo of quoted parent Eric

"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)."
