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!!”

Laura 2 reviews
$30 per hour for 1 child

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

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.

Yisel 1 review
$30 per hour for 1 child

Why should a family choose me as a nanny? I am Yisel from Colombia, responsible, honest, fun, open-minded, patient, loving, dedicated, happy and pet friendly person. I love spending time with children, helping them to grow up happy, sharing my culture with them, teaching them my mother tongue and learning new things. I am a language teacher in my country, I speak Spanish, English and French, I worked as a teacher in a daycare for two years and I have experience as a nanny for more than 6 years and 3 years of nanny sharing with the same families, I love helping my children reach their creative potential and develop a harmonic cognitive process. I believe that a variety of activities are essential for the development of children. Also, the closeness to nature and engagement in building things with their own hands will stimulate their eagerness to explore and experiment. I like the key "learning by playing" because it corresponds to reality and what I like doing with children. And you can be sure that your children will have rewarding experiences with me. It would be great to become your friend, contact person, and role model for your children. I love children and care about them, so their well-being and safety are most important to me. What activities would you like to do with your host children? Depending on the ages and the climate, I would do the following activities with the children: • 0 - 6 months: Early stimulation activities with water, sand, tempera and clay. Roll balls with sound, encourage crawling, rhythm with toys, feeding support and nursery rhymes. • 1 - 2 years: Activities that help them develop their early stimulation. Play with water balloons, threading games, fishing afternoon, sandbox, games with music, games with tempera paint and rope toys. • 2 - 5 years: Dance activities to the rhythm of music, building blocks, drawing pictures with different paintings, going up and down steps, drawing, painting silhouettes, taking them to the park, teaching them my mother tongue and helping them are their language.

“Yiyi worked as a part-time nanny for our son when he was 1 to 2 years old until we moved away to California. She is so kind, attentive, easy to work with and be around and helpful. She took our son out on adventures, did art projects with him ( she is a talented artist), read, sang, danced and actively engaged him. She is easy to communicate with, responsive and very reliable. I love that she speaks Spanish and English and exposed our son to Spanish. I don't think she was sick 1 day that she worked with us. She goes above and beyond, when I asked if she would be willing to come over when my husband had to be on a work trip while I was pregnant with our second child and had the flu, she said yes. I am forever thankful for her care during those very hard days. She became a part of our family and we still stay in touch. I highly recommend Yiyi!”
