Laura

Booked by 11 families in Mercer Island, WA

Hi! I’m Laura, a 23-year-old caregiver with 5 years of experience working with children of all ages, from newborns to school-age kids. I genuinely love spending time with kids and creating a safe, fun environment where they feel comfortable and happy. I enjoy doing crafts, reading stories, going on walks, and finding activities that keep kids engaged and active. I’m patient, attentive, and always try to match each child’s personality and needs. I’m also a big animal lover (especially dogs!), so I’m very comfortable in homes with pets and happy to help with pet care too. In addition to childcare, I can help with light cleaning, organizing, and running errands to make your day a little easier. I’m reliable, responsible, and always aim to make families feel they can trust me with their home and their kids.

“Laura did a wonderful job taking care of our daughter. Laura was very communicative, helpful, punctual, and professional, and got along really well with our five year old. She got her to take a nap and a bath (two things our daughter isn't super fond of), and she conversed and played well with her. We would highly recommend Laura to other parents, and hope we can have her come back again to take care of our daughter. ”

Booked by 6 families in Mercer Island, WA

Hi there, My name is Selay. I’m 30 years old and originally from Turkey. Spending time with babies and children is a true passion of mine. It brings me great joy to witness their curiosity as they explore the world around them. Caring for children has always been an important part of my life, not just as a job, but as a natural part of my family life as well. As the eldest child, I took on caregiving responsibilities at a young age. While my parents were working full-time, I was closely involved in caring for my younger sister from the time she was a baby, and I also helped look after many of my cousins. Growing up surrounded by children taught me so much and shaped me in many positive ways. I came to the United States as an Au Pair. I worked with the same family for three years, and during that time I also had the opportunity to work regularly with other families. Through these experiences, I have cared for children of nearly all age groups, including newborns. Over the past five years, I have developed extensive experience providing attentive, nurturing, and safe care for newborn babies during their most delicate and important early stages. With my current family, I began caring for their baby when he was just 1.5 months old, and we have been together throughout his entire growth journey. He is now 2 years old, and as he will soon be starting daycare, I am looking for a new position. My experience with newborns also inspired me to deepen my knowledge through professional training. I have completed birth and postpartum doula training, which strengthened my understanding of newborn care, postpartum support, and the emotional and practical needs of families during the early months. I am also currently completing Montessori teacher training. This has helped me better understand child development, independence, respectful caregiving, and how to create an environment where children can learn and grow at their own pace. Through all of these experiences, I’ve come to realize how fulfilling it is to work with children of all ages. Teaching them while also learning from them is truly a magical experience. If you’re interested, please don’t hesitate to reach out. I would love to talk about how I can support your family. Thank you, Selay

“Selay was great - she showed up on time and had great energy with our kids. Our kids enjoyed time with her and she put our kids to bed smoothly so we got to enjoy a quiet home when we came back!”

I am a creative, responsible, and independent individual with several years of experience working with families as both a nanny and babysitter in part-time and full-time roles. I genuinely enjoy caring for children and creating a safe, fun, and nurturing environment where they can learn and grow. I am dependable, organized, and able to adapt to the unique needs of each family I work with. Traveling has allowed me to become open-minded, flexible, and comfortable in different situations and environments. Family is very important to me, and I value building strong, positive relationships based on trust, respect, and communication. I take pride in having a strong work ethic, a positive attitude, and a genuine passion for helping others. I’m currently nanny for twins !!

Abba 6 reviews
$27 per hour for 1 child

Peace to you! My name is Abba. I grew up in Port Orchard, and have spent most of my adult life in Seattle. I enjoy being active and exploring my environment, which is what has always drawn me to child care! I most recently nannied a sweet and energetic 2 year old and had been working with the same family since October 2022. I’ve worked at kids camps, baby sat for years, and have 12 nieces and nephews whom I have often taken care of and helped raise. My favorite part about childcare is the excitement children often bring to any kind of activity, there is so much learning, exploring, and growing happening in our early years . As an adult its nice to be reminded of the everyday 'awes' of being a human! Not to mention, a privilege to take part in so many of someone’s “firsts”. I truly feel fulfilled in spending time and caring for children, and value mutual respect between kids and care-givers. I implement developmentally appropriate activities of all kinds into daily routines, to encourage habitual learning. I am an artist, which translates into fun crafts and sensory exploration activities for kids! I love the outdoors rain or shine and don’t mind facilitating activities that may be deemed “messy”. Additionally, I have a deep love of gardening and growing food, as well as participating in various forms of community. I value respect and care between myself and parents, as we are a team! I would love to chat and get to know you and your family, I also have a detailed resume I can share, I encourage you to reach out! Adult/Infant CPR & First Aid certified

“Abba was a full-time nanny four our daughter from age 1-3, and we were devastated when our daughter graduated onto preschool and Abba wasn't here every day anymore. I cannot recommend Abba enough - they're unbelievably caring, professional, easy-going, dynamic, communicative, and they always went above and beyond what was expected. You're lucky to get Abba as a sitter.”

"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."

"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)."
