Charles Kelley (Harper Smith)Charles Kelley and his wife, Cassie Kelley, welcomed their second child, son Archer Lancaster Kelley, on Sept. 16. He joins big brother Ward Kelley, who’s 9. “The hardest thing with Ward was, you know, we were so used to sleeping in till, like, 9, even 10 [a.m.],” Charles explained. “But now we’re kind of used to functioning on a little less sleep. “And so the fact that I’ll actually have a couple of months to kind of breathe and just enjoy this baby before we start the Christmas tour is going to be great,” he adds.
