A set of parents who lost one child to a rare disorder is welcoming a new baby in a heartwarming way.

Gloria and Steve Kimmel of Indiana lost their son Isaac to spinal muscular atrophy type 1 in 2015, PEOPLE reports. He was just 14 months old.

To honor him, the couple got matching tattoos. Each of them have one wing tattooed on their back, and when they stand side-by-side, the wings form a set.

“He was half of each of us, so we each had one of his wings to hold us,” Gloria, 29, said. “He was the angel that was holding us together when we were so lost without him. The tattoos are a reminder that he is always with us in spirit.”

In June, about two years after Issac’s death, the couple welcomed a baby girl, Claire. They had a photo shoot to celebrate her arrival.

Photographer Megan Miles incorporated the couple’s matching tattoos into one photo, laying baby Claire on the couples’ backs, making it look like Claire had a pair of wings.

“When I saw it for the first time, I saw our entire family,” Gloria says. “Like Isaac was there with us.”

Gloria’s sister shared the photo on Twitter where it quickly went viral, garnering more than 70,000 likes.

The couple said they were touched by all the compassion strangers from around the country showed them.
