Jinger Duggar: Pregnant With Baby #2?!

Is Jinger Duggar expecting a second child?

Fans think Jinger just dropped a major hint in a very subtle way on Instagram.

Earlier this week, Jinger announced that she would taking part in a quarantine musical challenge started by her mother-in-law.

Jinger posted a video of herself playing piano alongside Felicity.

“[I’m] joining in on [the] @swan4kids_pa challenge to play ‘He’s Got the Whole World in His Hands,’” Jinger, 26, captioned her post.

“I’m challenging @janamduggar [and] @chad_erinpaine to do the same!" she added.

"Would love for you all to join in as well! Post a video of yourself singing or playing, and tag @swan4kids_pa #healthyfitpregnancy.

"Challenge two others to do the same.”

At first glance, it may seem like a pretty straightforward post.

But what is that #healthyfitpregnancy hashtag doing there?
