Kailyn LowryOK, this is the way to kick off your weekend. On Friday afternoon, Teen Mom 2 star Javi Marroquin (Kailyn Lowry's hubby) posted the most adorable laughing baby video on Instagram. And the best part is that it's his own infant son Lincoln happily squealing away!

Oh wait, no, that's not the best part. The best part is what is delighting him so thoroughly -- his big brother Isaac, who is telling him in funny voices, "I love you."

Heart. Melted. Seriously, I think I'm bookmarking that and watching it whenever I need a pick-me-up, because with this kind of brotherly love in the world, things don't seem so bad after all.

He captioned the adorable video with, "Bond is unbreakable already." He tagged Kail in it too, and she of course shared it with her own social media followers.

Kail and Javi are doing such an awesome job raising their two little boys, and Javi's unquestionable acceptance and inclusion of his stepson Isaac is going to go a long way in nurturing that bond. Well done, you two.

How happy does this video make you?
