This handsome little devil! Teen Mom 2's Kailyn Lowry hopped on Instagram on Monday, Sept. 14, to congratulate her eldest son, Isaac, on his latest milestone: He just became a NYFW model!

The 5-year-old (who hails from Delaware) hit the runway at the Spring 2016 show for children's line Bound by the Crown on Sunday, Sept. 13. And from the number of excited posts shared via Instagram, it seems that Lowry, 23, could not have been more proud of her little boy.

"Isaac's first fashion show yesterday!" she captioned one cute family snap from the runway, which included both Isaac, Lowry, and her husband, Javi Marroquin. (Lowry shares Isaac with ex Jo Rivera. She and Marroquin also have a son, Lincoln, 21 months.)

But the gushing didn't stop there! Lowry, whose first children's book, Love Is Bubblegum, hits shelves in November, also shared a video of Isaac's runway strut. In it, you can see the grade-schooler happily waving to the audience while following behind a little boy in a suit. She captioned the clip, "Go Isaac!"

Making the most of NYC, Lowry also shared a short video of Isaac adorably attempting to hail a cab while wearing a T-shirt that read "Make it snappy."
