When I found diapers in my 15-year-old son’s backpack, my mind raced. Was he hiding something? Was it a prank? I couldn’t shake the feeling that something was off, so I decided to follow him after school.

He walked with purpose, heading toward a small house on the other side of town. Peeking through the window, I saw him gently lifting a baby from a crib, expertly changing the diaper. My heart clenched.

Knocking on the door, I braced myself. A girl—no older than him—answered with tired eyes. She looked shocked to see me. My son turned, his face filled with fear. “Mom, please, I can explain,” he whispered.

It turned out his friend’s older sister had a baby and no support. My son had been secretly helping, using his allowance to buy supplies.

I pulled him into a hug, tears in my eyes. He wasn’t in trouble—he was a hero. And I knew we had to help.
