Karen Fairchild & Jimi Westbrook Welcome Son Elijah Dylan!

Little Big Town band members Karen Fairchild and Jimi Westbrook have welcomed their first child!

Baby boy Elijah Dylan Westbrook was born on Friday (March 5) in Nashville, Tenn. He weighed 7 lbs., 14 oz., and was 19 and ¾ inches long.

"We've been waiting for this for a long time and can't tell you how thrilled and blessed we both feel," Fairchild tells People, who says Westbrook is a "natural" at fatherhood.

"Karen is going to be an incredible mom," says Westbrook of his wife, who had completed a degree in early childhood education before entering the music industry. "She has always been so good with children. Besides, she's done a great job raising me to become a responsible adult!"

Their bandmates will be sure to lend some helpful advice. Kimberly Roads Schlapman is mom to Daisy Pearl, 2 ½, with husband Stephen and Phillip Sweet is dad to 2-year-old Penelopi Jane with wife Rebecca.

"Our hearts are bursting with joy for Karen and Jimi," Schlapman says. "We have dreamed of this moment with them for a long time. We can't wait to welcome another little angel onto our bus."

Little Elijah will need to get packing soon, since the group, whose single, Little White Church from their upcoming album will be released to radio next week, are hitting the road again in May, joining Montgomery Gentry, Jamey Johnson and Jack Ingram on the Country Throwdown Tour.

The couple announced their pregnancy in October.

Congratulations to the Fairchild-Westbrook family!
