We love watching Leah Messer and her adorable twin girls Aliannah and Aleeah on Teen Mom 2, and despite some bumps along the way with Ali’s development, we’re happy to say the girls are currently happy and healthy. When were Leah’s daughters born?

On her episode of 16 & Pregnant, Leah gave birth to her twins on December 16, 2009. We can’t believe it’s been 4 years since then! They’re growing up so fast. It seems like only yesterday we were watching Leah’s first episode.

And Leah’s expecting another baby in the next couple of months with husband Jeremy Calvert! We can’t wait for Aliannah and Aleeah to be big sisters.
