Duck Dynasty’s Rebecca Robertson and husband John Reed Loflin are expecting baby number three!

Together, the couple have a 5-year-old son, Zane, and 2-year-old daughter, Holland.

The reality TV mom shared the news to social media on May 18. With a carousel of professional photos, her two children hold letters they “received” from the future little one, with sonogram photo attached to the inside of the cards.

“Looks like we may need a bigger couch,” she writes on Instagram. Per the post, baby number three is expected to make its arrival in November.

One of the cards reads: “Dear Big Sister, I can’t wait to meet you! Even though I haven’t met you, I already know I am gonna have the best big sister in the world & I can’t wait to play with you.”

Both mother Korie Roberston and sister Sadie were quick to express their delight and excitement, adding their joy of the news in the comment section.

In addition to adding a comment, the grandmother also posted two photos of her own.

“The BEST NEWS!! Grand baby # 8 is on the way!!! We can’t wait to meet you little one,” she writes.

Robertson is one of six children to Willie and Kori Robertson. While she is referred to in the family as their daughter, she was never legally adopted after the Robertson couple began fostering her in 2004.

Collectively, Willie and Korie have seven grandchildren, Robertson’s baby will take that number to eight come the fall.
