Interestingly enough, Jessa's older sister, 25-year-old Jill (Duggar) Dillard, is also expecting her second child with her husband, Derick Dillard -- another baby boy! The two welcomed their son, 1-year-old Israel, in April 2015.

"The next Dillard baby is a boy," Derick, 27, announced in a video posted to TLC's website last week. "Israel didn't really understand what was happening but he's just excited because other people are excited, so he's just excited about his new little baby brother."

"We're really excited about having another son," Jill added. "I know that Israel and this little one will be best friends."
