Gillian $28 per hour for 1 child

I am a passionate care provider. I bring this passion with me to every job that I do. I am creative, and fun, but also bring balance, and stability. I love working with children in a variety of settings. I have had the privilege of working with the same families for over ten years. I have also worked with children on the autism spectrum, and other special needs. Most of all, parents can trust me with their children. This is of upmost importance when choosing a care provider.

Tanya $15 per hour for 1 child

My name is Tanya, and I am the mother of two (daughter 17 and son 3). I would like to put my name out there for childcare for your little ones. Ideally, your child(ren) could come to my house, but I can also go to yours. I do have my 3 year old little guy who would be there or come with me. I am located in Fairwood Greens community in Renton, WA, and my home is a smoke free and no pets. All of us (except my 3 year old) are fully vaccinated. I can help with date nights, or I am even open to exploring an ongoing thing if there is someone who works nights or weekends and needs help. I know it can be hard to find childcare for those off hours. I have every other Friday off as well so a daytime slot could work there as well. I am happy to go over timing in more detail though. If you are interested and would like to chat more and get to know me beforehand, feel free to message me. We could even meet up at the park for a little meet and greet before you make any decisions. 😊

Booked by 1 family in Mercer Island, WA

I’m Princeton, a dependable and attentive pet sitter with hands‑on experience caring for both a dog and a cat in a home environment. Over the years, I’ve learned how to balance the different personalities and needs of each animal—whether that’s keeping a playful pup engaged with structured walks and enrichment or giving a curious cat the calm, consistent attention they prefer. I focus on creating a safe, comfortable routine that helps pets feel secure while their owners are away. From feeding schedules and medication reminders to exercise, grooming, and plenty of affection, I treat every pet as if they were my own. My goal is always to maintain their normal rhythm, reduce stress, and make sure they’re happy, healthy, and well‑cared‑for. Owners can count on me for clear communication, reliability, and genuine care that goes beyond the basics.
