Looks like the Stork might be paying another visit to Teen Mom Valley (a terrifying place full of dirty diapers and cankles), because Teen Mom 3’s Mackenzie Douthit has an acute case of baby fever! The only prescription? Even more babies. This girl's sister just gave birth to her very first kiddo, and it looks like Mackenzie just can't get enough of this bambino!

"Gannon's new baby cousin:) Melody Grace," Mackenzie posted to Instagram on April 28. "Uh oh I think me and Josh are getting baby fever :/"

Mackenzie and Josh are gearing up for their Spring 2013 wedding, and apparently they've sworn off sex until after their hotly-anticipated nuptials. But who knows how many buns will be baked in Mackenzie's oven after these two become man and wife...

Of course, we can't forget that Mackenzie has type one diabetes, and she told Dr. Drew (during the 16 and Pregnant reunion special) that if she gets pregnant again, it could be extremely dangerous. In fact, Mackenzie's first pregnancy was so high-risk that her doctor encouraged her to get an abortion!

"When I was 2 months preg. diabetic doctor told me to abort the baby cause there is a big chance I and/or the baby would die," Mackenzie tweeted on September 14, 2012. "Look at us now ;)"

Hopefully this gal will have a healthy and happy pregnancy when she and Josh do decide to get pregnant for round two.

Do you think Mackenzie and Josh are ready for another baby, or should they wait a couple years? Tell us what you think!
