The Mum Gave Birth To ‘Hidden Triplets’ After Shocking Late-Term Discovery

When Genna Knox became pregnant in 2019, she was thrilled to be giving her son, Liam, a sibling.

Knox was shocked to learn she was actually expecting triplets — at seven months along.

This was not the first surprise of the California teacher’s pregnancy. At her 20-week scan, the woman performing the ultrasound asked Knox if she was having twins.

The mom couldn’t believe it when she was told she was expecting triplets.

“She’s like, ‘Wait, you’re having twins?’ And I said, ‘No, I’m not,’” Knox, 42, told Today Parents, recalling what the technician told her.

“Then I looked up, and I could see clear as day that there were two babies,” she continued.

Seven months into her pregnancy, Genna and her husband, Kyle, decided to get a four-dimensional ultrasound to show their families.

The couple now has four kids — after initially thinking they would be a two-child household.

“She’s like, ‘Wait, you’re having twins?’ And I said, ‘No, I’m not,’” Knox, 42, told Today Parents, recalling what the technician told her.

Kaylee, Lily and Cecilia were born on March 21, 2019

It was then they realized they were actually expecting triplets, with the third baby hidden in what’s called “hidden triplet syndrome.”

“I barely remember anything else about the moment. I was in total shock,” Knox said.

“When the babies are very small, one baby can hide behind the other,” Daneshmand, who also treated Knox, told the outlet. “Typically by 26, 27, 28 weeks — the baby that’s been missed will suddenly appear.

The Knoxes’ three daughters, Kaylee, Lily and Cecilia, were born at 33 weeks, on March 21, 2019. The fraternal triplets spent a few weeks in the neonatal intensive care unit after they were born — but are now thriving.
