Kimberly Schlapman and husband Stephen just welcomed a second child to their family — or as a tweet from the singer's band put it, "Little Big Town just got a little bigger."

Meet their new arrival, Dolly:

"The New Year brought our family new love," Schlapman wrote in a caption on Instagram. "We're so excited to introduce you to Daisy's little sister, Dolly Grace."

Big sister Daisy, 9, looks on at the new bundle of joy adoringly while mom and dad smile for the camera in the cozy family photo Schlapman shared with the announcement.
