"Amina came and helped us out when our babysitter canceled last minute. She was great with our kids. Even our 11 month old son who has stranger anxiety warmed up to her."

Hello! It’s great to meet you ! I work as a substitute teacher during the school year and pick up occasional jobs here as well. I teach Kindergarten through twelfth grade and am very familiar and comfortable with that wide age range! Besides that, I have also worked in other school districts as an after school leader, where I was used to working one on one with students as well as leading large groups of kiddos as well. I have also nannied for a family with two babies, ages 2 1/2 and 9 months until I started working as a permanent substitute. I find kids’ energetic and kind personalities a joy to be around and I love working with kids for those reasons! I have a clean driving record and happily offer pickup and drop off from school if needed. I can offer school related assistance including homework help, arts and crafts, light tidying around the household, and anything else that I may be of help in. My priority is always to ensure that this is a great experience for both the family and children, as for me as a caretaker! Please let me know if you have any questions or concerns and I will be more than happy to answer them! I am excited to meet you and potentially work with your family and little ones! I am fully vaccinated as well as have all of the boosters and am CPR Certified for all ages.

I am an experienced pet sitter and have been taking care of animals for my entire life! I am great with dogs, cats, and other pets and can ensure they are taken care of properly.

Hi , My name is Brianna and i’m a senior in high school looking foward to being a babysitter for toddlers, or kids. I have much experience taking care of children since i was 15 and i would gladly enjoy being a babysitter for your kids or animals!! I’m not really a big fan of cats but would enjoy taking care of dogs, taking them on walks and keeping them in care.

Caring for a child means supporting their safety, growth, and emotional well-being with consistency, respect, and compassion. I bring those values to every family I serve. I am an experienced, energetic caregiver and mother, CPR/AED and CPI certified, with formal study in child development as part of my degree requirements. I am active, dependable, and thrive in supportive, structured environments that help children build confidence, healthy habits, and strong social skills. Beyond my professional experience, I volunteer with children in the special needs community and youth sports, which has strengthened my ability to adapt, lead with patience, and respond calmly in high-stress situations. I take pride in being fair, trustworthy, and genuinely invested in each child’s well-being. I would be honored to support your family and provide a loving, safe, and encouraging environment for your loved one.
