His wife, Jill Duggar Dillard, was enduring 70 hours of labor, but Derick Dillard was as cool as a cucumber… Or at least that's the perception he was giving off.

Nothing could be further from the truth.

"I was nervous," Derick told PEOPLE magazine, adding, "I didn't want to show that or make her more fearful."

As has been reported, things didn't go exactly to plan during Jill's delivery. She planned an at-home birth but had to be moved to hospital. There, Derek said he serenaded his wife with some of her favorite spiritual songs and read Bible verses in between her contractions.

Finally, doctors advised Jill to have a C-section, even though her original plan was to have an all natural birth.

"She had labored for so long," Derick said. "There's no shame in that, there's no shame in not progressing, there's no shame in getting a C-section."

Jill's mother, Michelle Duggar, was also in the delivery room through all the drama. She felt helpless.

"There were times I looked into her eyes during contractions where I wanted to cry. I know how horrific it is to go through that, and I did everything I could not to break into tears," Michelle said.

Of course, after baby Israel was finally born, all was right in the world… and suddenly Derick was no longer the coolest cat in the room, or even his household -- Check out those shades!
