Built-In Big Sis: A High School Babysitting Job That Became Family

For Lindsey Leavitt, babysitting wasn’t just a gig—it was family. As a mother’s helper and trusted caregiver to Milly & Mack during her senior year in high school, she stepped into a world that taught her more than she ever expected. Caring for two children with non-speaking autism wasn’t just about routines and responsibilities—it was about patience, deep connection, and learning to communicate beyond words. But Lindsey’s role didn’t stop there. She was also a built-in big sis to Sarah's oldest neurotypical daughter Morgan, giving advice, sharing laughs, and being a steady presence in her life. Now, after one semester at Penn State, she reflects on how that year shaped her—the challenges, the love, and the unexpected lessons that still stay with her. More than a paycheck. More than a babysitter. This is what real caregiving looks like. #BuiltInBigSis #Neurodiversity #LessonsInLove
