It's no secret that we're completely in love with Teen Mom 2 star Leah Messer's adorable twin girls, Aliannah and Aleeah. We've watched them grow up before our very eyes, following Leah every step of the way down the bumpy road of teenage motherhood.

For 20-year-old Leah, these little girls prove that miracles really do happen — and that's why she gave them the middle names Hope and Grace.

As most Teen Mom 2 fans know, Aliannah Hope suffers from an unspecified developmental condition that doctors have been working tirelessly to identify and treat. Her condition has hindered her ability to walk on her own, and she needs glasses to help correct her vision.

Despite the hardships, little Ali never stops fighting — and she's already beating the odds! Leah's also confident that doctors will soon have the answers she's been searching for since December 16, 2009.
