Five years ago, as she was treated for stage 3 breast cancer, the thought of having children was the furthest thing from Aly Taylor's mind
Aly, who was 24 at the time, had been trying to get pregnant when doctors discovered her cancer.
After she underwent a double mastectomy and chemotherapy, doctors informed her and her husband, Josh, that radiation treatment had made her unable to conceive. So the couple considered adoption.
The high school sweethearts from Louisiana, who are featured on the TLC show "Rattled," ended up adopting a baby girl, Genevieve, in 2015.
However, when Genevieve was 9 months old, Aly started feeling nauseous and dug up an old pregnancy test she had in the house. The couple was stunned to learn she was pregnant.
"Oh my goodness, it was crazy,'' Aly told Hoda Kotb and Kathie Lee Gifford on TODAY Wednesday. "Because it wasn't like doctors told us there was a slim chance that it would happen, it was that it was impossible.
"It's truly a miracle."
One month into Aly's pregnancy, Genevieve's birth mother contacted the couple to say she was pregnant again. She asked if they were interested in adopting Genevieve's biological sister.
The woman's due date was only days from the due date for the Taylors' daughter, Vera, who is now a year old.
"She said, 'Aly we're not expecting you to adopt this baby because you're pregnant,' but immediately my heart was drawn to this baby,''' Aly said in an episode of "Rattled." "I just could not imagine saying no to another baby when at one point we didn't know if we'd ever have children."
The Taylors temporarily moved to Kentucky from Louisiana so they could be present for both births, which occurred only 11 days apart.
Just like that, they were a family of five after welcoming Genevieve's biological sister, Lydia, and then Vera.
"It's so much better than we could've ever dreamed,'' Josh, 32, said on TODAY. "If you had asked us five years ago, 'Give us your dream, write it down,' our dreams would come up so short of where we've ended up."
Aly, 30, has now been cancer-free for five years.
"You know, being a breast cancer survivor, thinking that this wasn't possible, that I might not be here, (and) that we would have these three beautiful blessings,'' Aly told Hoda, a fellow breast cancer survivor.
The couple have since heard from people struggling with infertility, adoption and cancer who were inspired by their story on "Rattled," which focuses on five couples adjusting to parenthood.
"The goal is to give people hope,'' Josh said on TODAY. "To know that when it's dark, it's gonna get better."
