Sweet Newborn Photos Capture the Devastating Final Moments of 1 Twin's Life

When looking at William and Reagan Brentlinger's sweet newborn photos, you'd never suspect that anything was wrong with either of these beautiful babies. However, this photoshoot will serve as one of the Brentlinger family's main reminders of William, as he passed away just 11 days after his and his sister's birth.

At her 23-week appointment, Lyndsay Brentlinger and her husband, Matthew, were told that William would be stillborn. "He just had a bunch of abnormalities," Lyndsay told ABC News. "The left side of his heart was not functioning." But as fate would have it, William was born with his tiny heart beating and was able to go home with his family to enjoy his short life. "They were the happiest 11 days of my life," Matthew said.

To honor William's life, the Brentlingers turned to photographer friend Lindsey Brown, who squeezed them in for a beautiful photo shoot that would give the family memories of William to cherish for years to come.

"Photographing the babies was very bittersweet." Lindsey told POPSUGAR Moms. "They both looked so perfect. You never would have known anything was wrong with sweet William." Lindsey says that even though the Brentlingers were some of the strongest and kindest people she's met since becoming a photographer, this shoot was still extremely difficult.
