Hi! I’m Sloan and I’m from NC but I currently live here in Miami for college! I absolutely adore kids and I have worked with them for many years! I’ve babysat kids in my neighborhood of all ages and in high school, I took classes where I had the opportunity to learn all about children and their development and needs through the Early Childhood Education class which also allowed me to work everyday with the kids in the preschool that was attached to my high school! I also took a Teacher Cadet class where I picked to work with Kindergarteners where I had to make lesson plans and teach the class! I spent every morning with them for 9 weeks and would spend any of my extra days working with them as well!
Throughout middle and high school, I spent a lot of time volunteering to take care of kids, whether it was helping out at summer camps, after-school programs, or babysitting for family friends. I also work at a daycare. Those experiences sparked my passion for working with children and taught me how rewarding it can be to be a positive part of their lives. I’ve always made it a priority to create a safe, welcoming environment where kids feel comfortable and cared for, while also making sure they’re having fun—whether that means turning everyday tasks into games, coming up with creative activities, or just being someone they can laugh and talk with. I bring a bright, upbeat personality to everything I do, and I love being the kind of person kids can look up to and trust. For me, it’s not just about keeping kids safe and entertained—it’s about making them feel seen, valued, and excited to be themselves.
Hi! I’m Paulina — a warm, responsible, and energetic caregiver with a background in health and education. I love working with kids of all ages and always aim to create a fun, safe, and engaging environment. Whether it’s helping with homework, creative play, or bedtime routines, I bring patience and positivity to every moment. Looking forward to supporting your family!
Hey my name is Kira, I’m 23 and currently reside in Miami, FL. I absolutely love kids, have 1 of my own, and hoping for more to come. I’ve been in the childcare field for over 10 years whether it has been teaching vpk, preschool or taking care of infants and other children. Kids love me, I love to do little activities and experiments as well as exploring new things. I look forward to being there for you and your family! I also like to bake and cook with the little ones as well as story time and more. I can’t wait to get started! Hope to see you soon!
Hi there, I'm Mailed, a Social Communication graduate from USM (a Venezuelan university). I specialize in caring for both children and seniors. Since the age of 18, I've embraced the role of a nanny, tending to little ones from 8 months to 13 years old. My duties span driving, crafting, meal preparation, and engaging them in educational games to nurture their skills. Being the youngest among my siblings, I've lovingly watched over 6 of my 10 nieces and nephews as they grew, even caring for twins. I have a genuine affection for children and share a warm connection with elderly adults. Respectful, attentive, and dedicated, I find joy in uplifting spirits, especially those of our furry friends, particularly dogs. Looking forward to the opportunity to bring warmth and care to your loved ones. Warm regards, Mailed.
