Scott Lambert still bemoans not being able to look into his grandson's sky-blue eyes one last time on Aug. 29.

"If you could look in those eyes and not see God in them, I just don't know," he said. "He just had so much love in them. That's what I'm going to miss."

Robbie Moore, 1, died at Children's Hospital Medical University of South Carolina in Charleston while awaiting a heart transplant. He died from a brain hemorrhage as the result of a blood thinner taken in preparation for a mandatory procedure, his grandmother Lynn Lambert said.

Robbie had survived cardiac arrest and being diagnosed with cardiomyopathy, a chronic disease of the heart muscles, before his first birthday.

"To watch him pull through everything he did, and see the hope in the doctors' eyes, and for him to be gone because of one little risk. It's heartbreaking," she said. "I know it's God's will, but I'm heartbroken."

Robbie's death was the second loss the Belvedere family has endured in the past few months. In May, Mrs. Lambert's son-in-law, Nick Moore, drowned in a boating accident. The family has grappled with Robbie's death for the past two weeks, and are hoping that The Robbie Moore Heart Fund will help their daughter, Brittany Moore, survive the financial burden she carries while coping with her loss.

"It's been like a juggling act for her," Mrs. Lambert said. "It's amazing that she's been able to handle this. She's so strong."

Mrs. Moore devoted most of her time to caring for Robbie in his last few months, so she had little time to mourn her husband's death, Mr. Lambert said.

The Lamberts are caring for their daughter's oldest son, Nicholas, 3, while Mrs. Moore copes with the losses. Mr. Moore's parents, Herbert and Emma Moore, have also helped.

Mrs. Lambert said she has found comfort in knowing that hundreds of people beyond her family cared about Robbie. Many have reached out through the fund set up to help pay for his medical needs. So far, almost $4,000 has been raised, Mrs. Lambert said. Brittany Moore pays as much as she can on the medical bills, but there's still hundreds of thousands left to pay, Mrs. Lambert said.

"It really gives us renewed strength that there's been such a great response," she said. "Some give $5, some give $500."

The Lamberts plan to keep the fund open for a few months, Mr. Lambert said. He hopes that it will keep the memory of his grandson alive for the family and strangers.

"He had no intentions of leaving this world without a fight," he said. "I don't have many heroes in this world. My dad was one; this baby was another."
