What began as a shocking surprise in the delivery room has grown into a story of love, resilience, and acceptance that has touched millions of people around the world.

Baby Ayla Summer Mucha, who was born in December, has captured hearts on social media after her parents began sharing her journey to raise awareness about an ultra-rare condition that gives her what many lovingly call a “permanent smile.”

Her parents, Cristina Vercher, 21, and Blaize Mucha, 20, were overjoyed to meet their newborn daughter. But shortly after her birth, doctors explained that Ayla had been born with bilateral macrostomia, an extremely rare condition in which the corners of the mouth do not fully fuse together during fetal development.

💙 The diagnosis came as a complete surprise.

“Blaize and I were not aware of this condition, nor had I ever met someone born with macrostomia,” Cristina shared. “So it came as a huge shock.”
According to medical literature, only a handful of cases had been documented, making the condition so uncommon that even the doctors caring for Ayla had never encountered it before.

Adding to the surprise, none of the prenatal ultrasounds had detected the condition. Following Ayla’s cesarean birth, doctors needed several hours to determine exactly what they were seeing.

“I was already overwhelmed after the C-section,” Cristina recalled. “When I first saw Ayla, it was obvious because she was so tiny. We were instantly worried.”
For several anxious hours, the family waited for answers.

💔 Like many parents facing an unexpected diagnosis, Cristina found herself wondering if she had done something wrong during pregnancy.

Doctors quickly reᴀssured her that Ayla’s condition was completely beyond her control and that nothing she or Blaize had done had caused it. After genetic testing and further evaluation, Ayla was officially diagnosed with bilateral macrostomia.

Although the condition is often recognized because of its appearance, it can also affect important functions such as feeding, latching, and suckling. Because of these challenges, reconstructive surgery is commonly recommended.

Cristina said the family knows surgery will involve carefully reconstructing the corners of Ayla’s mouth while aiming to minimize scarring, although they still have concerns about the recovery process.

🌸 Rather than hiding their daughter’s differences, the family chose to embrace them.

A few months after Ayla’s birth, they created the TikTok account @cristinakylievercher to document her journey, educate others, and connect with families facing similar experiences.

Their videos—showing Ayla smiling, giggling, playing, and wearing adorable outfits—have reached millions of viewers. One clip alone received more than 47 million views, with thousands of people leaving messages of encouragement.

Many commented on how beautiful and joyful Ayla is, while others expressed a desire to learn more about her rare condition.

💖 Although some hurtful comments appeared online, countless others quickly came to Ayla’s defense, flooding the family with kindness, encouragement, and support.

Cristina hopes their story reminds people to treat everyone with compᴀssion.

“Be kind and accepting of all people. Conditions such as this could happen to anyone. You can’t control the personalities of other people, but you can choose kindness.”
Today, the overwhelming love from people around the world far outweighs the negativity.

❤️ Cristina says she is grateful they chose to continue sharing Ayla’s journey because it has allowed her to connect with other parents facing similar challenges.

For their family, every smile, every milestone, and every memory is something to celebrate—and they have no plans to stop sharing the remarkable story of their beautiful little girl, whose “permanent smile” continues to brighten the lives of millions.
