It's T-minus just a few more hours until Teen Mom 3's Mackenzie Douthit gives birth to her second child! This Oklahoma native is scheduled to deliver her baby girl on February 7, a whopping three weeks before her due date. So why the early delivery? Mackenzie suffers from Type 1 diabetes, and her frequent hospitalizations and blood sugar dips have made her pregnancy more than a little high risk.

At the time of writing this article, Mackenzie and her husband, Josh McKee, are in hospital waiting to welcome their mini cowgirl into the world, but fear not — Mackenzie took some time out of her schedule to snap one final picture of her baby bump.

"Last picture ;) 37 weeks," Mackenzie posted to Instagram along with a photo of her bare baby bump.

All we have to say is OMG! Mackenzie's belly is huge (second children are often bigger than first children), and she definitely looks like she's ready to pop. Meanwhile, Josh is in the background chilling in a hospital chair with his eyes covered, presumably because he doesn't want the Instagram Public to be blinded by his handsome face.

If you're as excited as we are about internet-meeting Mackenzie's beautiful baby daughter, check back in with Wetpaint Entertainment. We'll let you know as soon as this bundle of joy makes her appearance in Teen Mom Land!

In the meantime, send a few positive thoughts Mackenzie's way … labor is no walk in the park!
