The “world’s oldest baby” was born in Ohio last week from an embryo that had been frozen for more than 30 years.

Thaddeus Daniel Pierce was born via adopted-IVF on July 26 to parents Lindsey, 34, and Tim Pierce, 35, who said the fertilized embryo was first frozen in May 1994, MIT Technology Review reported.

“We had a rough birth, but we are both doing well now,” Lindsey told the outlet. “He is so chill. We are in awe that we have this precious baby!”

“The baby has a 30-year-old sister,” the proud mom said, adding that her hubby was just a toddler when his son’s embryo was created.

The couple said they were floored by the fact that a program to adopt embryos even existed.
