Hi, my name is Fiona. Im 24 years old, I am looking for something long term and full time/part time. Occasional date nights too:) In previous years I took a class called child development and learned basic early child development course work. While in that class I got the opportunity to work with kids ages 3-6 at my schools preschool, created lessons, and fun activities for them to do. By doing that I am now child development certified. I also have worked a day camp during the summer, in past years, working with grade school aged kids. I started nannying about 5 1/2 years ago, taking care of family friends and so on. I love being around kids and creating fun activities for them to do, such as arts and crafts, like making slime and etc. I also have been a lifeguard in the past and so I am CPR and First Aid certified. I hope to be in consideration and to meet you and your family! :)

“Fiona is a very punctual and sweet sitter. She’s very involved and my child loves her.”

Hi, my name is Tatar. I’m a college student with hands-on experience working in a daycare, where I cared for children ages 0 to 3. I truly enjoy spending time with young children and creating a safe, warm, and engaging environment where they can learn and grow. Through my daycare experience, I’ve developed a patient, caring, and attentive approach to childcare. I enjoy planning age-appropriate activities such as educational games, puzzles, reading, arts and crafts, and outdoor play. I’m also comfortable helping with meals, tidying up after the children, and maintaining their daily routines. I understand that every child is different, and I always take the time to learn their personality, needs, and routines. I also value clear communication with parents and am happy to provide regular updates throughout the day. My goal is to be a reliable and caring person you can feel comfortable trusting with your little ones. I would love the opportunity to support your family and make your day a little easier!

I am a professional nanny living in Belltown but am willing to to travel around the metro area to care for children. During my days I am constantly taking kids to parks, gyms and community centers, play zones and walks: We read books, do art, sing songs and discover fun throngs kids love. I’ve taken children to the Ferris wheel, zoo, museums, the aquarium, Seattle City center and more. My background is completely different as I was in a high level stressful career and chose nannying and caregiving to change my life. I am CPR certified and first aid certified. In my past life I was a qualified OSHA trainer so I have a high focus on safety. During naps I am willing to cook, clean and handle pet needs. Would love to find a couple of families I could connect with and provide care nights and weekends! Enjoy all ages and will cater to their needs! Happy to connect with families traveling to Seattle that need childcare.

I have always had a passion for working with and taking care of children. I am the baby in my family, but it was my biggest joy being able to watch after my 5 younger cousins growing up. I think that is what sparked my interest. I was a youth counselor one summer in grade school, my first job I worked as a tutor for Kumon Learning Center, tutored a family friend's son for over a year, worked as an assistant for special needs children and adults. The start of covid I worked for College, Nannies, & Sitters, and at a preschool with children ages 1-5. During covid I moved to Cle Elum and nannied for a family of 4. When I moved back I worked for another preschool/daycare. I am extremely positive and patient, I am also very attentive and professional. I put the children's needs first, and love to build friendships that leave a lasting impact. I am a great listener and I love to interact. I will teach your children how to be responsible and polite, yet still be their silly, creative selves.

"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."
