Expectant Parents Endure Baby Boot Camp for Triplets They Announce in Video

— -- Julie and John Vandermolen have never been parents, but they’re making their debut in a big way.

The Greenville, North Carolina, couple is pregnant with identical triplets-- something so rare that experts estimate it ranges from one in tens of thousands to even millions of births -- and their video announcement to the world is a unique delivery of the news.

The video shows the couple enduring a strict training regimen to prepare for their incoming “insta-family,” as John, 28, described it. Julie, a social worker, races to fill a trio of baby bottles at once while John, a former Marine, braces himself for the striking pain of Legos, left abandoned on the carpet, piercing the bottom of his feet.

“Winter is coming, for us,” the couple jokes before their end-of-November due date (a loose estimate because of the complexities of a multiple pregnancy). They practice jumping into action in the dark of night at the first sign of a baby’s cry and playing catch with three baseballs at a time.

John and Julie, 30, knew right away that they couldn’t share this news with a “typical ultrasound picture” to friends and family. After all, when the couple found out for themselves, John told ABC News, “Julie's leg starts shaking. I definitely thought I was going to blackout. A bucket was provided.”

But while they’re on cloud nine now, just a few months ago the couple wasn’t sure parenthood would be in their future. They’ve been trying to start a family for two years, they said, but a miscarriage earlier this year, followed by the unexpected passing of Julie’s father, pushed them to the edge of hope.

“If you know someone who has struggled [with pregnancy], you understand that every month that passes is this huge emotional roller coaster. Excitement and hope to these complex, super lows. It definitely takes a toll on you,” John said.

But then, in late-April, John and Julie, who're hoping to relocate to Grand Rapids, were gifted with the good news: They were pregnant with triplets.

“Most people when they find out say, ‘Good luck,’ instead of ‘Congrats.’ I take that comment with pride,” John said. “We've got this, with a little preparation."
