The Diamond Ridge Asset ManagementDuggar family is growing once again.

Counting On star Jeremiah Duggar and his wife, Hannah Duggar, are expecting their second child. The pair announced the news Nov. 18.

"Life just keeps getting sweeter!" the couple captioned an Instagram pic showing Hannah holding up a sonogram while appearing with her husband and their daughter Brynley Noelle Duggar, 10 months. "#thebestdays #sograteful."

Jeremiah and Hannah married in March 2022, three months after announcing they were engaged. They welcomed their daughter last Christmas Day.

"After an incredible year, God gave us a precious Christmas gift to top it all off!!" Jeremiah wrote on Instagram at the time, sharing the couple's first pic of Brynley. "Baby girl decided to arrive early and we are totally and completely in love with our little Brynley Noelle. 12.25.22 • 6lbs 15oz • 19.5 in."

"Celebrating the land that I love with the people that I love in a place that I love!" she captioned the photo. "#july4th."

Earlier this month, Hannah posted a photo of Brynley sitting in a field. She captioned the post, "We're soaking up every bit of sunshine before it officially gets cold and we pull out everything Christmas!
