When my son and his wife asked me to watch their two-month-old baby while they went shopping, I expected a quiet afternoon of rocking, feeding, and soft lullabies. Instead, his cries turned desperate, sharp, and relentless. No matter what I tried, he wouldn’t calm down. When I checked his diaper, what I saw made my hands tremble. I grabbed my coat, rushed to the hospital, and realized that sometimes a grandmother’s instinct can save a life.
