“Lauren just has rough pregnancies,” he shares. “I’m sure there’s a lot of moms out there that feel that way. But when Lauren gets pregnant, the whole getting sick first trimester and then you’re done just has never really applied to her.”

“It’s just really sad because I feel like I can’t do anything to help, except order Taco Bell at 11:30 at night to put something in her stomach,” he shares.

Despite the hardships, Thomas Rhett says Akins is “such a trouper” and he’s never heard her “really be like, ‘I’m sick.’ "

“You can just kind of see it a little bit on her face,” he says. “But we’re going to get through it and we’ll have a beautiful fourth daughter out of it.”

“I feel like I’ve got the ropes down as to what that looks like, being a dad to a girl. So when I found out we were having a fourth, I was like, well, we’ve already got the clothes, I know how to do this, this is just round four of it,” he says.
