In the tearful second episode of the faith-based mini-documentary "Mike and Carrie: God & Country," Carrie Underwood and husband Mike Fisher discuss the multiple painful miscarriages the singer suffered after the birth of their son Isaiah.
Their now 5-year-old boy was born half a decade into their marriage, and they knew immediately they wanted him to have a sibling.
"I'm a planner," Underwood said with a laugh. "I like to know what's happening all the time."
Though Underwood got pregnant fairly quickly, "months in" she suffered a miscarriage.
"It sounds wrong when you say it," Underwood confessed, "but it's one of those bad things that happens to other people. You know what I mean? It's like so many things in the world, it's not something that you ever envision yourself having to deal with."
But Fisher, a former professional hockey player, was convinced he and the country superstar would have another son.

"I was just kind of wrestling and probably the most honest I've been with God ever in my life," Fisher explained. "And I heard not audibly, but I just... sensed that God told me we're gonna have a son and his name's Jacob."
"Not much longer [afterward], we were pregnant and we lose another baby," Fisher continued.
Soon after, a "bawling" Underwood crawled into bed with her sleeping son and had her own heart-to-heart with God.
"I just had an honest conversation with God, and I told him how I felt," she revealed. "I was hurt, I was a little angry. Of course, you feel guilty for being mad at your creator."
"And I told him I needed something," she went on. "We needed to have a baby -- or not ever. Because I couldn't keep going down that road anymore."

"And we went in later on that day and had an ultrasound. And it's like, 'It's all OK. Everything's OK,'" she says. "So we were like, 'Jacob. This is Jacob.'"
Jacob's parents soon learned the significance of his name.
"The story of Jacob," Fisher explained, "[is that] he wrestled with God through the night, and he wouldn't let him go until he got his blessing. And we weren't demanding that he give us this blessing. We were just being honest with him."
Jacob Fisher celebrated his first birthday in January.
