Time has gone by incredibly fast and no one knows that better than the Teen Moms. Teen Mom 2 star Leah Messer gave birth to her first kiddo with husband Jeremy Calvert (she has twins Aliannah and Aleeah Simms with ex-hubby Corey Simms) seven months ago, and the little bambina is growing up before our eyes!

In a recent photo Leah posted on Twitter, the now 7-month-old baby is sitting on her own. Oh yeah, and she’s decked out in a pink leopard-print onesie with a matching hat. Addie is definitely starting to come into her own looks, though she resembles her older sisters. But one thing’s for sure — she’s a total cutie.

The last time we saw the baby, she was a all toothless smiles and giggling in her crib. Now, the little girl is going to be 8 months in less that two weeks and we can look forward to seeing Leah tweet photos of her first tooth and Vine the little gal’s first steps.

Are you amazed by how much Adalynn has grown? Do you think she looks more like Leah or Jeremy? Sound off in the comments below!
