Javi Marroquin continues to be free of all flaws. This studly Air Man has seamlessly made the transition from World's Best Husband to World's Best Father, and he's once again slaying the Teen Mom universe with his perfection. Javi and Teen Mom 2's Kailyn Lowry just welcomed their first son into the world, and lil' Lincoln's arrival has only cemented this dude's love for his wife.

"Being a mom is one of the hardest jobs out there," Javi mused to no one in particular on December 3. "Having a newborn I've noticed everything kail does for us. I try and keep her sane tho."

There's no denying that Kailyn does a lot for her family. Not only does she stay up all night feeding her new little man, she takes care of both Linc and Isaac by herself during the day. She must be exhausted, so luckily girlfriend has Javi's uber-appreciative shoulder to lean on.

"Appreciate everything you do!" Javi tweeted to Kailyn. "I don't know how you do it, but you find a way to continuously go above and beyond. I love you."

Sigh, time to go inflate our trusty blow-up boyfriend. Can you believe how cute Kailyn and Javi are? We can't!
