Jessie James Decker Daughter Vivianne labor and Delivery

The birth of Jessie James Decker‘s daughter may have been picture perfect, but her labor and delivery didn’t exactly go according to plan.

During a routine checkup with her doctor, the country singer and Eric & Jessie: Game On reality star was given some unexpected news: baby girl was on her way!

“He was like, ‘You are going to have this baby today. It’s time, she’s really huge and I don’t want you to go any longer,’ ” James Decker, 26, tells PEOPLE.

The sudden due date explains the full face of makeup worn in the hospital pictures.

“I got so much flack for being dolled up in that Instagram photo, but I went to the doctor for my weekly check-up … of course I was dolled up because I like to leave the house that way,” she says.

But after 14 hours of labor, James Decker was not progressing.

“I never dilated past six centimeters so I had to have an emergency c-section, which was devastating for me,” she recalls. “I was yelling and screaming at everyone. I wanted to have that special labor and moment of having a natural birth.”

Despite her disappointment, the first-time mom admits it was all worth it: on March 18 she and husband Eric Decker welcomed daughter Vivianne Rose.

“I wanted a really sweet, classic Southern name,” she shares of the couple’s choice.

Their “traditional” pick still has plenty of fun flair to it, however. “I love the movie Divine Secrets of the Ya-Ya Sisterhood and I loved the way the dad would call her, ‘Viviaaanne.’ So that’s how we say it, too — it’s not just Vivianne. I love it,” she explains.

Decker recently signed with the New York Jets and the family of three will be settling in the Big Apple. Although the mother-daughter duo haven’t ventured out into the city just yet, James Decker isn’t one to shelter her 6-week-old.

“I’ve been letting her see everything. I want her to see things and be aware of her surroundings — I think it will make her smarter,” she says. “It’s also going to be dangerous for me being in the city with all that shopping. I’ll definitely take her shopping.”

After working her way through feeling “like a bum” during her pregnancy and gaining “a lot of weight and a double chin,” James Decker is bouncing back with a little help from breastfeeding.

“Luckily, I have a ton of milk. I’m the crazy girl that’s in the studio pumping,” jokes James Decker, who just released her new EP, Comin’ Home. “I’m freezing it now — there is so much. It’s a special feeling, intense and the sweetest thing. You are watching her get the most amazing nutrition for her body. It’s beautiful.”

As for how Decker is handling first-time fatherhood?

“He’s ridiculously amazing,” James Decker says. “He changes all the diapers willingly. [He] gets up with her most of the nights because I’m a hard sleeper — it’s not that I don’t want to wake up, but she cries and I don’t hear it sometimes. He just gets up and does it and doesn’t wake me.”

The season finale of Eric & Jessie: Game On airs Sunday at 10 p.m. on E!
