Sarah $22 per hour for 1 child

Hi, I’m Sarah and am a senior at the UW studying Geography and Information systems (GIS). I’m born and raised in Seattle and have been working with kids for the past few years. I’ve worked at a daycare, where I spent a year specializing in the toddler (2-year-old) room, as well as volunteering at elementary summer camps. Right now, I spend my weekends teaching a program for 8-12 year olds, and last year, I worked with a nonprofit running after-school activities for kids who needed extra support. Family is important to me, last year, I had the joy of helping care for my infant nephew when my sister welcomed him into the world. From infants to pre-teens, I love connecting with kids through play and learning. When I’m not babysitting or studying, you’ll find me curled up with a book or when I can find the time exploring new hiking trails.

Iva $22 per hour for 1 child

From a young age I have been interested in working with children. At birthdays, family gatherings, and holidays, I was always the one watching and playing with all of the younger kids. In high school, I began babysitting and made my first earnings by babysitting for a lovely family after school each day. More recently, I have been interested in child development and am studying psychology to understand the milestones of development and understand how children can be supported early on to enable their full potential and support their emotional, physical, and intellectual development. Most recently, I worked as an Enrichment teacher for a summer camp program. As such, I was responsible for a group of 25 kids and lead STEM based lessons and crafts. My position as a summer teacher has not only augmented my respect towards teachers, as I have understood how challenging it is to guide, observe, and mentor a cohort of kids, but it has also helped me build an invaluable set of skills. In my experiences, I’ve learned to be attentive, vigilant, patient, observant, and understanding. The emotional lives of children are just, if not more, complex than those of adults. They must face difficult and big emotions having only a limited set of skills to manage them. As such, I prioritize listening and respecting the feelings that children I work with have. What may seem trivial to the adult perspective may be much more significant for a younger mind. When facing challenges, I always start by listening. Most often, we just need to be heard. In addition to emotional safety, I also prioritize situational safety by always observing behavior and context as many things can be prevented when de-escalated early on. Caregiving is at the heart of every relationship as we all require someone to rely on. As a person, I am very sympathetic, understanding, welcoming, supportive, and reliable – all aspects that I’ve learned through my personal, professional, and academic experiences and believe are vital to proper caregiving.

"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."
