Mia and Chad Kaercher’s route to parenthood took an astonishing turn when, while their surrogate was pregnant with their son, Mia discovered she was also expecting-after years of believing conception was impossible.
A Fast Match After Years of Struggle
The Kaerchers turned to surrogacy when multiple surgeries and IVF cycles failed. With only two embryos left, their clinic suggested a gestational carrier.
> “Our finding of a surrogate was incredibly serendipitous,” Mia told News Of Los Angeles. “We were told it was about a two-year process… two days later a miracle happened and our surrogate was matched with us.”
The carrier had already cleared every screening and was scheduled to travel for another couple who then conceived naturally, freeing her to meet the Kaerchers.
Double Joy in One Year
The embryo transfer worked on the first try-news Mia calls “surreal.” Weeks later, feeling off, she took a pregnancy test.
> “I did not find out I was pregnant until almost 16 weeks… the last thing I considered,” she said. “My doctors were shocked!”
Both pregnancies progressed smoothly, delivering:
- Woods via surrogate at 3 months old
- Cohyn via Mia at 8 weeks old
Life With Twiblings
The infants-dubbed “twiblings” because they share DNA but grew in different wombs-already share a nursery and daily bath time.
> “Our son is never not smiling… he really notices his sister,” Mia said. “They spend all day right next to each other.”
Once intensely private, the couple now chronicle their journey online to encourage others facing infertility.
Key Takeaways
- Surrogacy can succeed even after extensive fertility treatments
- Natural conception can occasionally follow failed IVF
- Twiblings offer siblings close in age from the same biological parents
Mia calls motherhood her “ultimate dream come true,” crediting her husband as “the greatest partner and dad I could ever dream of.”
