Mariah Carey and Nick Cannon were the proud parents on Barbara Walters’ ABC 20/20 special, showing off their six-month-old twins Morrocan and Monroe and revealing new details about her difficult pregnancy.

Carey and Cannon have been hyping the ABC special on their Web site, and have created another site just to show off the kids called DemBabies.

It would be a sad turn if the children became a props to promote their parents’ careers or eventually their own, but Cannon surprisingly is hoping they don’t choose show business as a career.

“I just want them to strive for something greater than entertainment,” Nick has said.

“I’m one of those believers in teachers, professors, heart surgeons. That’s what I’m rooting for. If I could get a scientist, that’d be amazing.

“I want them to get a Ph.D.”

Cannon was nothing if not a doting husband and father.

“When he’s nice, he’s the best guy in the world,” joked Carey. “You know, he’s a man, Barbara. Let’s call it what it is.”

Cary had a disastrous first marriage to record mogul Tommie Mattola.

For Mariah, carrying the twins was a harrowing ordeal, fraught with forced bed rest, false labor and several trips to the emergency room.

Carey previously endured a miscarriage, and resorted to fertility and hormone treatments to get pregnant, which caused bloating and weight gain.

She revealed that she even needed help just get out of bed and use the restroom.

“I had serious back problems,” Carey said. “I was afraid I wasn’t going to be able to walk properly again. It was a huge strain.”

The babies were delivered by Cesarean section at 35 weeks on April 30, after doctors grew concerned about the health of mother and babies.

A live version of Carey’s her hit song, “Fantasy,” played in the background.

“The only reason I wanted the live version was so they could hear the applause upon entering the world,” Carey said.

Carey’s decision to give birth after 40 put her in a high risk group where the risk of complications is elevated.

She revealed that she suffered from high blood pressure, preeclampsia and gestational diabetes, while she was carrying the twins.

“I don’t think I understood the enormity and the magnitude of what it (pregnancy) really does to your body; it’s not just, ‘Oh, you don’t look pretty and you have a bump…’ I was carrying two babies,” she said.

“Unless somebody’s been through it, it’s difficult to understand what I went through because my pregnancy was very unique in terms of what happened to me,” she added.

On today’s ABC program “The View,” Walters also talked about her interview with Mariah Carey and Nick Cannon, which will provide the first look at the babies.

“They’re adorable!” Walter’s crowed on the show.

To get pregnant, Carey took fertility treatments, which continued 10 weeks into her pregnancy to ward off the possibility of a miscarriage

“It was good, but it was scary,” Nick said about the pregnancy.

The number of women giving birth into their 40s and 50s and beyond is at record highs, according to the Centers for Disease Control and Prevention.

In 2007, 105,071 women aged 40 to 44 gave birth, the highest rate since 1968; the birth rate for women 45 to 54 was 7,349, an increase of 5% in just one year.

Experts are concerned about the increased risk of maternal health problems for women who give birth over 40, ranging from cardiac complications to potentially even a higher risk of developing breast cancer, according to
