Hi! My name is Julia and I'm a compassionate child care professional with over 15 years of experience. My background includes being a preschool teacher for an established hospital's child development center as well as 10+ years experience as a career nanny. I have a strong knowledge of early child development that includes implementing age-appropriate activities, supporting emotional development, and maintaining a nurturing and safe environment. I also have several years of experience babysitting infants through school-aged children, and have studied psychology as well as child development.

Booked by 2 families in Mercer Island, WA

Hi there, my name is Nishadi! I am a true and native SoCal girl who found the beautiful PNW about 9 years ago. I love catching sunsets, hiking, and a good puzzle when it’s raining. I am currently pursuing a degree in Interior Design and planning my wedding for October 2026! My goal is to make the parents’ lives happier and easier as I care for their children by keeping them safe and entertained. I’ve been a nanny ever since moving here and have loved all of the families I’ve cared for and are still with them. I value a good fit with a family and being a part of the family as I get to know you. Looking forward to a fun opportunity with your children!

“She’s very neat, organized, on time, caring, affectionate, sweet and punctual. She arrived on time. Understood all the instructions. Came exactly on time even though it was last minute. Left the house an baby extremely clean. My daughter was really happy as well. Very impressed and will be hiring her again!!”

Looking for a family to work with Hello seattle families. I’m Laura from Colombia, I was an aupair but now a I’m a nanny, I have 6 years of experience with babies (from 6 to 10 months) and kids (from 2 to 7 year old) I have my driver license and my own car. I’m happy to provide you references and more information I’m looking for some extra hours happy to provide my resume.

“Laura has been a nanny for our two children (a 5-year old girl and a 22-month old boy) for over a year. Laura has predominantly helped our family with the morning duties related to both of our children (helping them to wake up, feeding them breakfast, getting them cleaned/dressed for the day, preparing snacks/lunch and driving our daughter to pre-school). She is an extremely reliable caretaker for our children, making safety and boundaries a priority while keeping it fun for each of them. The kids each love her and looking forward to their time with her every day. Laura is great at giving each kid age and developmentally-approritate activities to enjoy. And she is extremely supportive of the childrens' emotional needs. Laura does a great job of balancing each child's hectic morning schedule and tasks, is reliable/on-time, communicative with us and adaptable when we have new or adjusted requests/schedules. We would recommend Laura to anyone looking for a reliable, loving, responsible caretaker for their child or children.”

Booked by 1 family in Mercer Island, WA

Hi! I’ve been caring for kids, pets, and helping households in different ways for many years. I started babysitting in high school and continued on and off through college, and also worked as a camp counselor in high school with kids going into kindergarten. I’m additionally a proud aunt to two boys (Ian is 3, and Ellis was just born on May 2!) and have spent a lot of time caring for and babysitting them over the years. I’m naturally very creative, patient, attentive, and emotionally aware, and I care a lot about making sure kids feel safe, listened to, respected, and genuinely seen. I’m also reliable, responsible, and organized, so parents can feel comfortable knowing things will actually be handled well and consistently. I enjoy engaging with kids in a real way rather than just supervising them passively, whether that means creative activities, outdoor time, games, helping with routines, or simply being a calm and supportive presence. Animals have also been a huge part of my life. I grew up with dogs, worked at a dog groomer in high school, fostered dogs through the ASPCA and Furever Home Rescue in New Jersey, and adopted my own rescue dog through Big Dog Rescue Project in 2020. I currently work professionally through Rover and have experience with walks, drop-ins, overnight care, routines, medication support, and caring for pets with different personalities, needs, and energy levels. I take pet care very seriously and understand how important trust, communication, safety, and consistency are when someone is caring for a beloved animal. Beyond caregiving, I’m also highly organized and happy to help with general household support such as tidying, organizing, errands, light cleaning, meal prep, pet-related cleanup, receiving deliveries, watering plants, or helping keep things running smoothly overall. I’m adaptable, detail-oriented, calm under pressure, and genuinely enjoy helping create a more peaceful and supported environment for people. I’m new to Urban Sitter and haven’t collected reviews here yet, but you can find reviews on my Bambino babysitter profile, or check out my LinkedIn page. Happy to provide both to you when we connect.

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.
