I'm a retired homemaker who has successfully raised three kids in this area. I live with my husband and 2 small dogs in Bellevue. We have three grandchildren under the age of 12, they live locally and we see them frequently! I love kids, people and pets and I like to help. I have many years experience as a parent, and have experience being a grandparent too. I can sit, tutor, play and cook. I enjoy running errands and I take direction well. Kids like me, and I'm good with babies too. In my spare time I enjoy reading, baking, board games, shopping, walking the dogs and babysitting.
“Dina was very professional and great with consoling my 3 week old newborn and spending time with my 3 year old. He really loved talking with her and was sad for her to go. It was so nice to have her help!”
Hi I'm Grace. I grew up in Indiana, I've been in WA for about 8 years now. I've always taken care of children, of all ages. I've taken care of newborns to pre-teens. I’ve been babysitting through UrbanSitter for a while now and I’m pretty experienced with all age ranges.
Hi! I am a nanny and a teacher. And passionate about what I do!! In the past 3 years I worked for several families. I was an au pair for 2 years and provided care for 2 different families, both with 2 kids and a baby. I currently take care of a boy of 18 months old since he was 2 months old. I graduated in pedagogia in Brazil and taught kids from 6 months old to 6 years old. After having babysitting in the USA I have the knowledge and the experience to offer the best care according to the parents needs. I am vaccinated and CPR/First Aid certificated.
“Very kind sitter and my step kids had fun with her! She’s quick to respond and reliable. ”
Hi family! I’m Diana – an energetic, kind, and experienced nanny and teacher who genuinely loves working with kids of all ages. With over six years of experience in education and childcare, I bring a blend of patience, organization, and a fun-loving attitude to every family I work with. I’m a graduate teacher and have worked with children ranging from 2 months to 6 years old in both classroom and home settings. I started babysitting my niece and nephew. I took care of a wonderful family with three children (now 2, 4, and 6 years old) for two years, helping with everything from morning routines and after-school activities to meals and bedtime. I’m currently caring for a 7-month-old baby, which has further deepened my experience with infants. I love spending time outdoors with children—whether it’s walks, playdates, or playground adventures—and I always try to nurture their creativity through art and craft projects. I’m CPR and First Aid certified and always strive to create a safe, supportive, and engaging environment for kids to thrive. I’m excited to continue supporting families in my area and would love to connect! Feel free to reach out, Diana
“Diana was prompt, kind, and played lots of arts and crafts etc with my 4yo, and very understanding when we ran a bit late. My daughter had a great time!”
Nice to meet you families! My name is Melissa and I have been working as a caregiver for the last 8+ years. I truly enjoy the company of children and nurture their artistic side. A little bit more about me. I have a background on Architecture and Graphic Design. I love art & crafts, and doing these projects with kiddos is fun (except for the mess). I have a lot of experience with kids between 2-8y/o and experience with babies from 3 months-18 months. I’m excited to be part of your crew of back up childcare!!!
“Melissa was great with our 10 month old he was very happy! They played and she helped him with nap time! Thank you Melissa!”
