Can you believe it's almost been four months since Teen Mom 2's Kailyn Lowry gave birth to her second son? This starlet's pregnancy was hardly easy, but after months of anxiety and emotions, she popped out Baby Lincoln on November 16 and has been lucky in love with her bundle of joy ever since.

Lil Linc' has been in our lives for a while now, and we cannot believe how much he's changed in just a handful of months. When this kind made his triumphant debut over the holidays, he looked like the spitting image of his dad, Javi Marroquin (pouty lips and all!), but these days the little man is finally starting to look like his mom!

Check out this recent picture of Lincoln that Kailyn posted to Instagram. First of all, he's ridiculously sweet (look at that smile!), but get a load of that facial expression. We definitely see some of those Lowry genes coming through!

Either way, there's no denying that Lincoln is one good looking dude — we can't wait to see how he grows and changes during his first year of life!

Do you think Linc looks more like his mom, or his dad? Hit the comments and weigh in on this super-important issue!
