A family of five, is now a family of nine after a Waco mother gave birth to not one, not two, not three, but four babies on Monday.

It was all a big surprise to the parents and the doctors and nurses at Baylor Scott and White Hospital Hillcrest.

“We went from having a single baby, and then found out I was having triplets,” said Vivian Van Gorder, mother.

Vivian and Chris Van Gorder never expected what life would throw at them, originally thinking they were pregnant with just one baby, then later finding out they were expecting triplets.

The couple received another shock on Monday evening during her C section.

“At delivery, we delivered those three babies that we expected and I reached in and felt an elbow,” said OB/GYN specialist Dr. C. Tony Dunn.

“And then when they said, ‘Oh we found a fourth baby’ and I was like oh my god, oh my god are you serious, are you serious,” said Van Gorder.

One delivery, two boys and two girls, making up 40 fingers and 40 toes.

“We were well into the three and they ran in and said there’s a fourth, and we didn’t believe them at first, I’ll never forget everyone’s reaction,” said Amanda Hutchens, Neonatologist at Baylor Scott and White Hillcrest.

Making them the first set of spontaneous quadruplets in Waco history.

“It really is hard to keep all the numbers of arms and legs and heads straight because you’re only looking at one area of the abdomen at a time with the ultrasound,” said Dr. Dunn.

In fact, quadruplets are so rare that there’s only an average of about 220 each year in the United States, and about 219 of those pregnancies are with fertility assistance.

“So this was really unusual, and statistically this really is a one in a million,” added Dr. Dunn.

Within five minutes, all four were born at about five pounds each, Baby A: Erik, Baby B: Tristan, Baby C: Clare…

“And then Baby D is unknown,” said Van Gorden.

Those babies have three older siblings, ages 4, 9 and 10.

“Two girls and a boy and now we have two boys and two girls, so that’s seven total,” said Van Gorden.

They also have a family of doctors, nurses, and the entire Waco community who already love them.

“I’m just so humbled and amazed and both Vivian and I are so grateful to God,” said Chris Van Gorden.

The family won’t know until the babies are grown or they do DNA testing on them if they are identical twins. Doctors say because they each had their own sacks, those chances are unlikely.
