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. ”

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!”

I have been babysitting and working with kids since I turned 13 and started walking to babysitting jobs in my neighborhood. I love going on walks, reading, and doing crafts! I currently work at a general contractor coordinating our high school and college internships. I am looking for occasional nanny jobs.
“Emma was great! On time, engaging with our son, and listened well to instructions for the day. She was responsive and had a rave review from the kiddo when we got home!”

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!”
