On Tuesday, Jan. 20, 2026, the Grammy winner and her husband, Spy Kids actor Daryl Sabara, revealed the birth of their first daughter, Mikey Moon Trainor, who arrived via surrogate on Sunday, Jan. 18. While the couple is known for their “all about the family” lifestyle, the shift to surrogacy for their third child has sparked a wave of conversation, prompting Trainor to get candid about the medical realities that led to the decision.
“It wasn’t our first choice, but we had endless conversations with our doctors on this journey, and this was the safest way for us to be able to continue growing our family,” Trainor told People in an exclusive interview following the announcement. For a star who has built her brand on radical transparency from her traumatic first C-section to her recent health overhaul, the move to surrogacy isn’t just a personal milestone; it’s a public statement on the complexities of maternal health.
A History of “Horror Stories” and Medical Necessity
To understand why Mikey Moon arrived via surrogate, one has to look back at Trainor’s previous, often harrowing, experiences with pregnancy. While she carried her two sons, Riley, 4, and Barry, 2, both births were marked by significant medical hurdles. After Riley’s birth in 2021, Trainor revealed he was “breech” and struggled with breathing issues, spending his first five days in the neonatal intensive care unit (NICU).
The emotional toll was even heavier. Trainor has been vocal about being diagnosed with PTSD after that first delivery, describing the feeling of being “trapped” on the surgical table while her newborn was rushed away.
“Usually when you’re being sewn up for 45 minutes, you’re like, ‘Look at my gorgeous baby.’ But I was laying there alone,” she previously shared with People. These struggles continued during her second pregnancy with Barry, where she managed gestational diabetes, a condition that she says “rattled” her and served as the initial catalyst for her recent health focus.
Addressing the Noise: Weight Loss vs. Wellness
The timing of the announcement has led to some online speculation regarding Trainor’s dramatic 60-pound weight loss throughout 2025. As the singer hit the spotlight with a leaner physique, some fan theories suggested that surrogacy was chosen for aesthetic reasons or to maintain her new look. However, Trainor has been quick to shut down those “whispers,” clarifying that her physical transformation was actually a byproduct of her medical journey, not the reason for it.
In early 2025, Trainor confirmed she had used Mounjaro (a GLP-1 medication) under medical supervision to address health issues following her second pregnancy. She has consistently framed her fitness journey as an effort to be “the strongest version” of herself for her children.
“I’ve been on a fitness journey since I got healthy, and it started when I was pregnant and I had gestational diabetes,” she told KIIS FM in November 2025. Her team emphasizes that the decision to use a surrogate for Mikey Moon was strictly based on “medical safety” and doctor recommendations to avoid further high-risk complications.
The “Superwoman” Surrogate and a New Chapter
Despite the medical necessity, Trainor describes the surrogacy experience as a “beautiful” and deeply emotional process. In her Instagram announcement, she gave a heartfelt shout-out to her “incredible, superwoman surrogate,” noting that the family had formed a close bond with her throughout the pregnancy. The singer also revealed a sweet family detail: big brothers Riley and Barry were the ones who chose Mikey’s middle name, “Moon.”
“I want people to know that surrogacy is just another beautiful way to build a family. It’s not something to whisper about or judge,” Trainor said, according to The Independent. By sharing her story, she continues her streak of breaking down the “perfect mom” archetype, proving that every path to parenthood is valid, whether it’s through “science, trust, or teamwork.”
As Meghan Trainor and Daryl Sabara settle into their new lives as a family of five, the world is finally getting a clearer picture of the journey that led them to this moment. While the headlines have been filled with joy, the path to welcoming Mikey Moon was paved with medical caution and deep reflection.
Here is everything we know about the latest addition to the Trainor-Sabara household and the circumstances surrounding her birth:
- The Birth & Arrival: Mikey Moon Trainor officially joined the world on Sunday, Jan. 18, 2026. Her birth was announced via a joint Instagram post two days later, featuring a carousel of intimate photos, including a teary-eyed Meghan holding the newborn for skin-to-skin bonding. The couple expressed profound gratitude to their “incredible, superwoman surrogate” and the medical teams at the hospital.
- The Sibling Dynamic: Mikey joins big brothers Riley, 4, and Barry, 2. In a sweet nod to their involvement, Meghan revealed that the boys were actually responsible for choosing Mikey’s middle name, “Moon.” Riley has reportedly taken his “big brother” duties very seriously, even bringing photos of his sister to school to show his classmates.
- The Medical Decision: The shift to surrogacy was not a matter of convenience but of safety. Following high-risk complications during her first two pregnancies, including a breech delivery with Riley that led to a NICU stay and a diagnosis of postpartum PTSD, doctors advised that carrying a third child would pose significant risks. Meghan described the choice as the “safest way” to continue growing their family after “endless conversations” with their medical team.
- Clarifying the Weight Loss Rumors: Addressing online speculation that linked her surrogacy to her recent 60-pound weight loss, Meghan has been firm: her fitness journey was a reaction to a gestational diabetes scare and a desire to be physically strong for her kids. She has openly admitted to using Mounjaro under medical supervision to manage her health after her second pregnancy, but maintains that the decision to use a surrogate was purely to avoid the physical trauma of another high-risk delivery.
- Confirmed Future Plans: Despite the new arrival, Meghan isn’t slowing down for long. She is scheduled to release her seventh studio album, “Toy With Me,” on April 24, 2026, and will kick off her “Get In Girl” Tour in June. For now, however, the family is in a “bonding bubble,” prioritizing privacy as they navigate their first weeks with a baby girl.
- What Remains Speculation: While fans have been curious about the identity of the surrogate, her name and personal details have been kept private to respect her privacy and the legal agreements in place. Any reports claiming to know the surrogate’s identity remain unverified rumors.
