It's been a little over two weeks since Teen Mom 2's Kailyn Lowry and Javi Marroquin welcomed their son, Lincoln Marshall Marroquin, into the world, and you know what that means. Time for Javi to go back from whence he came — the U.S. Air Force. Javi's paternity leave is officially over, and he returned to work on December 2, leaving our girl Kailyn all on her lonesome!

Kailyn has her hands more than full with Lincoln and her first son, Isaac (not to mention her fleet of pets), and she's definitely stressing about Javi leaving. "Nervous for tomorrow," Kail tweeted on December 1. "Javi goes back to work and I have both boys on my own for the first time! Learning as we go!"

Kailyn will have to put most of her attention on Lincoln thanks to the fact that he's nursing 24/7, and she's worried she won't be able to pay enough attention to Isaac. "I'm still getting comfortable with nursing so I feel like I don't have enough hands for Isaac," she explained to a fan.

Luckily, Kailyn won't have to nurse Linc quite as often (or for as long) once he gets a little bit older, plus she'll have much more time for Isaac when he settles into a regular nap routine! But still — wish this gal luck on her first day without Javi's helping hands!
