They grow up so fast!

Jessa Duggar recently took to Instagram to share a new picture of baby No. 2, Henry Wilburforce Seewald!

“Where has the time gone?” she commented on the picture celebrating his one-month birthday. “[One] month old and 12 pounds of chubs!”

Henry is the second child of Jessa and her husband, Ben, who are also parents to one-year-old big brother Spurgeon.

The couple have wasted no time playing catchup with her parents (who have 19 children), considering they haven’t even been married for two-and-a-half years and they already have two adorable baby boys!

In the past, Jessa has been candid about wanting a large family — and has opened up about looking into adoption as a way of expanding her family.

“We would love to have children of our own, and we would also love to adopt,” she gushed before Spurgeon was born. “It’s something we are constantly praying about.”

Lately, the entire Duggar clan has had a lot to celebrate!

In addition to the birth of little Henry, Jessa’s big sister Jill is also pregnant with her second little boy; last year, Jinger married soccer player Jeremy Vuolo and there are definitely some more weddings in the future — as Joy-Anna announced her engagement and Joseph revealed he’s courting!
