Krissy Adler of Penn Township, who is set to have triplets on Father's Day 2020, with daughters, Wren, left, and Willow.

Krissy Adler heard two words an expectant mother never wants to hear from an ultrasound technician.

“Oh, my.”

Concerned, Adler and her husband, Chris, asked if there was anything wrong.

What the Penn Township couple heard was unexpected and startling.

“Honey,” the technician said, “you're having triplets.”

Krissy Adler snatched the forearm of the technician and squeezed. Eyes narrowed. Teeth grit.

“Don't you lie to me!” Krissy Adler bellowed.

It wasn't a lie.

It was a reality and a rare one at that — only about 1 in 10,000 pregnancies result in triplets. It's a reality the couple has had seven months to wrap their heads around.

Now, on the verge of welcoming the three newest additions to their family — on Father's Day no less — the couple is preparing for history at UPMC Magee-Women's Hospital in Pittsburgh.

“They told us this will be the first natural birth of triplets there in 20 years,” Chris Adler said. “Usually, it's a C-section when it comes to triplets, but they think she can give birth naturally.”

Krissy is prepared.She gave birth naturally to her two daughters, Wren, 3, and Willow, 4.Krissy, 29, was a petite 123 pounds pre-pregnancy. She's 156 pounds now and doctors estimate that each of the triplets weighs between 5 and 6 pounds.Krissy, a 2009 Knoch High School graduate, said she never expected to have to give birth to three more children — and certainly not all at one time.“I'm not too scared,” Krissy said with a nervous chuckle. “These three in my belly are pretty smart cookies.”Krissy is four weeks overdue for triplets.That's why doctors at Magee want to induce now. They will induce at 9 p.m. Sunday — a day after the couple's six-year wedding anniversary.“She's 36 weeks,” Chris said. “They told us usually it's 32 weeks for triplets.”The couple doesn't know the sex of the babies; they decided to keep that as one last surprise.Chris, whose farm is called Adler Acres and who is also a part of a tree removal family business known as Adler and Sons, is hoping for boys.“Our business is Adler and Sons, and right now we have daughters,” Chris said.Chris, who is 34 and a 2004 Knoch graduate, said each of the three babies will have his or her own doctor and nurse in the delivery room.“They put together a whole team,” Chris said.

The couple raises Texas longhorns, horses, miniature horses and American Mammoth Jackstocks (donkeys) on their farm.“Weird herd,” Chris said, laughing.Now they will have a human herd of their own.The couple's two daughters are grasping the implications of their mother's pregnancy.Well, almost.“My oldest sometimes thinks I'm going to give birth to horses,” Krissy said, chuckling.Chris and Krissy both admitted that seeing their family size go from four to seven overnight is a bit overwhelming.Luckily for the couple, they said they have a large family, a big house and plenty of support.“It's going to be all hands on deck,” Krissy said. “We are very blessed and fortunate.”
