Peering into the ultrasound screen four months into pregnancy, parents can just begin to detect their little one’s tiny facial features. A little nose. Eye sockets. the curve of a lip, if you look closely enough.

But when first-time Ringgold, Ga., parents Brian and Lisa Shook saw their daughter on the screen four months in, they didn’t need a magnifying glass to see that something was wrong.

“You could see her skull wasn’t a round shape,” the mother remembers. “It was actually more like a clover.”

As the pregnancy progressed, the Shooks knew that their baby was going to need significant surgery. But it wasn’t until shortly after Baby Layla was born in 2011 – when reconstructive surgeon Dr. Larry Sargent visited them in the neonatal intensive care unit – that they realized just what they were in for.
