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

“#BabySeewald is growing fast!” she captioned the image. “Already practicing swallowing, sucking a thumb, and actively moving arms and legs! So excited at the feeling of these first baby kicks!”

At 20 weeks along, the 19 Kids and Counting star, 22, is seen wearing a black T-shirt with her long hair in a side braid.

The reality star also posted an ultrasound video of her first baby with husband Ben Seewald, set to Andrew Peterson’s 2010 song, World Traveler.

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.”

#BabySeewald is growing fast! Already practicing swallowing, sucking a thumb, and actively moving arms and legs! So excited at the feeling of these first baby kicks! #UltrasoundVideo #20Weeks –with @ben_seewald “For you formed my inward parts; you knitted me together in my mother’s womb. I praise you, for I am fearfully and wonderfully made. Wonderful are your works; my soul knows it very well. My frame was not hidden from you, when I was being made in secret, intricately woven in the depths of the earth. Your eyes saw my unformed substance; in your book were written, every one of them, the days that were formed for me, when as yet there was none of them. How precious to me are your thoughts, O God! How vast is the sum of them! If I would count them, they are more than the sand. I awake, and I am still with you.” – Psalm 139:13-18
