Jimmy Carter is a 10-year-old boy who has visited many places around the world. But unlike most travelers, Jimmy “sees” these places from his mother’s back. Born with blindness and disability, Jimmy depends completely on his mother Anna and needs round-the-clock care.

Jimmy has a wheelchair, but they have never enjoyed using it. Every day, Anna carries Jimmy on her shoulders and helps him walk a short way with support. Together, they have traveled to many countries, visiting museums and taking wonderful photos to share happy moments.

Before each trip, Anna makes a plan and calls the travel companies to make sure they understand the situation. She always wakes up early to prepare meals, help Jimmy get dressed, and take care of all his needs. It is difficult, but she has made up her mind to give her son the best life she can provide.

When not traveling, they enjoy simple pleasures at home. They often ride a special bike together through their neighborhood, meeting their friendly neighbors. Over time, these neighbors often praise Anna for her courage and care toward her son.

Anna still remembers how her heart “broke” when she learned her son was blind for life. It took years to overcome those feelings of hurt. “Being a mom, my life is different,” she says, “but I will never stop being there for Jimmy because he makes my life meaningful.”
