Six years ago to the day, Leah Messer's life changed forever: The West Virginia native became a young mother to two beautiful daughters Ali and Aleeah. And now, the "Teen Mom 2" cast member is lovingly reflecting back to this special milestone -- on the ladies' birthday.
"2 of the 3 reasons I'll ALWAYS remain standing on my own two feet!" the 23-year-old shared on Facebook, along with a snapshot of her gals decorating a Christmas tree. "These precious little girls have been the reason I've held it together through it all, the good and the bad. I don't know where I would be without them!"
From there, Leah remembered that unforgettable moment she first became acquainted with the twins -- specifically, this emotional scene from "16 and Pregnant":
"Mommy will never forget that feeling when Dr. Hunter placed you on me at 8:09 and 8:10 NOW 6 years ago," Leah continued. "My heart for the first time skipped a beat and I knew what true love really was at that very moment! I'm so blessed to call you both my daughters. You make mommy proud each and every day!"
Beautifully said, Leah. Be sure to offer your well wishes for Ali and Aleeah in the comments!
