His parents, Matt and Melissa Graves, said in a statement today, "We will forever struggle to comprehend why this happened to our sweet baby, Lane."
"As each day passes, the pain gets worse, but we truly appreciate the outpouring of sympathy and warm sentiments we have received from around the world," they said.
"We will solely be focused on the future health of our family and will not be pursuing a lawsuit against Disney," they added.
The Graves said they hope to keep their son's "spirit alive" through the Lane Thomas Foundation.
"It is our hope that through the foundation, we will be able to share with others the unimaginable love Lane etched in our hearts," they said.
Walt Disney World Resort President George Kalogridis said in a statement today, "In the wake of this tragic accident, we continue to provide ongoing support for the family, which includes honoring their request for privacy."
Disney Chairman and CEO Robert A. Iger said in a statement last month, "As a parent and a grandparent, my heart goes out to the Graves family during this time of devastating loss."
