Jessa (Duggar) Seewald's little boy is getting big!

Seewald and her husband Ben's second son, Henry, is already 5-months-old and they can't believe it.

On Saturday, Seewald took to Instagram to share a photo collage to show just how much her son has grown over the months. She captioned the collage, "Growing up too fast!"

Henry is seen wearing a series of white onesies with colorful ties, which each show his age by the numbers, from one month to five months.

Seewald welcomed Henry in February and he joins his big brother Spurgeon Elliot, 1.

The family has been adjusting to their newest addition and talking about the struggles on their reality show, Counting On.

"Things have been a little more busy in the Seewald house," Ben explained in an episode. "One adjustment going from one child to two is there are so many diapers and they pile up so fast. We gotta take the trash out a lot more often."
