Mom-to-be Jessa Duggar shared an updated baby bump photo via Instagram Wednesday.

“At #22Weeks, #BabySeewald now weighs just over a pound,” the reality star, 22, captioned the selfie.

The 19 Kids and Counting star and her husband, Ben Seewald, announced their pregnancy news in April, not long after sister Jill Duggar gave birth to her first child with husband Derick Dillard.

The Instagram image comes amid a child molestation scandal involving brother Josh Duggar, 27, who sexually assaulted Jessa and sister Jill when he was a teenager.

“Like in Josh’s case, he was a boy, a young boy in puberty and a little too curious about girls,” Jessa said. “And that got him into to some trouble.”
