Frozen embryo from 1994 born as world’s oldest baby

A baby boy born over the weekend holds the new record for the “oldest baby.” Thaddeus Daniel Pierce, who arrived on July 26, developed from an embryo that had been in storage for 30 and a half years.

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


Lindsey and her husband, Tim Pierce, who live in London, Ohio, “adopted” the embryo from a woman who had it created in 1994. She says her family and church family think “it’s like something from a sci-fi movie.”

“The baby has a 30-year-old sister,” she adds. Tim was a toddler when the embryos were first created.

“It’s been pretty surreal,” says Linda Archerd, 62, who donated the embryo. “It’s hard to even believe.”

Three little hopes

The story starts back in the early 1990s. Archerd had been trying—and failing—to get pregnant for six years. She and her husband decided to try IVF, a fairly new technology at the time. “People were [unfamiliar] with it,” says Archerd. “A lot of people were like, what are you doing?”

They did it anyway, and in May 1994, they managed to create four embryos. One of them was transferred to Linda’s uterus. It resulted in a healthy baby girl. “I was so blessed to have a baby,” Archerd says. The remaining three embryos were cryopreserved and kept in a storage tank.

That was 31 years ago. The healthy baby girl is now a 30-year-old woman who has her own 10-year-old daughter. But the other three embryos remained frozen in time.

Archerd originally planned to use the embryos herself. “I always wanted another baby desperately,” she says. “I called them my three little hopes.” Her then husband felt differently, she says. Archerd went on to divorce him, but she won custody of the embryos and kept them in storage, still hopeful she might use them one day, perhaps with another partner.

That meant paying annual storage fees, which increased over time and ended up costing Archerd around a thousand dollars a year, she says. To her, it was worth it. “I always thought it was the right thing to do,” she says.


Things changed when she started going through menopause, she says. She considered her options. She didn’t want to discard the embryos or donate them for research. And she didn’t want to donate them to another family anonymously—she wanted to meet the parents and any resulting babies. “It’s my DNA; it came from me … and [it’s] my daughter’s sibling,” she says.

Then she found out about embryo “adoption.” This is a type of embryo donation in which both donors and recipients have a say in whom they “place” their embryos with or “adopt” them from. It is overseen by agencies—usually explicitly religious ones—that believe an embryo is morally equivalent to a born human. Archerd is Christian.

There are several agencies that offer these adoption services in the US, but not all of them accept embryos that have been stored for a very long time. That’s partly because those embryos will have been frozen and stored in unfamiliar, old-fashioned ways, and partly because old embryos are thought to be less likely to survive thawing and transfer to successfully develop into a baby.

“So many places wouldn’t even take my information,” says Archerd. Then she came across the Snowflakes program run by the Nightlight Christian Adoptions agency. The agency was willing to accept her embryos, but it needed Archerd’s medical records from the time the embryos had been created, as well as the embryos’ lab records.

So Archerd called the fertility doctor who had treated her decades before. “I still remembered his phone number by heart,” she says. That doctor, now in his 70s, is still practicing at a clinic in Oregon. He dug Archerd’s records out from his basement, she says. “Some of [them] were handwritten,” she adds. Her embryos entered Nightlight’s “matching pool” in 2022.
