A newborn girl was born in Australia with a unique genetic issue that even the doctors were surprised by. But everything is well for Ayla Summer Mucha since she has the sweetest grin that can make anyone happy.

Ayla was born with bilateral macrostomia, an uncommon disease. It is an extremely unusual disorder in which the corners of the mouth do not fuse correctly when in the womb. Ayla is now a TikTok star for her condition because netizens can't get enough of her gorgeous smile.

Cristina Vercher and Blaize Mucha gave birth to Ayla in South Australia. Her parents were taken aback by her uncommon condition after she was born. According to the New York Post, only 14 examples of this condition were reported in a 2007 research published in the Cleft Palate-Craniofacial Journal. It is so uncommon that the physicians at the hospital where Ayla was delivered viewed her case as the first.

"This made the situation much more terrifying because it took many hours for a doctor to respond." More challenges arose as a result of the hospital's lack of understanding and assistance for such an uncommon disease. "As a mother, all I could think about was where I did wrong, especially because I had been so pedantic throughout my whole pregnancy," Vercher explained to the New York Post.

Thankfully, Ayla is OK, and her smile has made her a TikTok celebrity! Despite her parents' regular communication with physicians regarding her health, Ayla has already captured hearts with her charming grin.

"I'm glad we left the video up since I've spoken to a lot of mothers who have had similar situations." "Because we are so proud, we will not stop sharing our experiences and favorite memories," Vercher continued.

Keep smiling, Ayla.
