Leah Messer recently learned the reason behind her daughter Aliannah's developmental delays.
In an interview with InTouch, the Teen Mom 2 star reveals that her four-year-old child has a rare and incurable form of muscular dystrophy.
"We were scared because we didn't know what her future was going to look like, but we always pushed for answers," Messer told the magazine. "We never gave up, and we never will. We'll do everything we can to make sure Ali has the life that she needs."
