wenty-one-month-old Ryan Roberts has only a few weeks left to live, and his mom, Diane, has only one request -- she wants other parents to see their children smile.

According to NBC, Ryan was born with Down syndrome and a congenital heart defect. During a recent surgery, doctors told Diane and her husband, Erik, that there was nothing else they could do for their son's heart. The couple then made a painful decision to stop Ryan's supportive care and sign a DNR

When friends and family began to ask Diane and Erik how they could help and what they could do, they would say that they didn't want anything.

“I said, just go create a memory with your kids. Just go put a banana split down in front of your kids for dinner and watch their faces light up. No chicken, rice and broccoli tonight, just ice cream. They're going to remember that forever,” Diane told HLN TV. "Watch them smile."
