Five weeks ago, Brody Allen’s parents were told that their 2-year-old son’s rare form of brain cancer meant he had two months to live.

The boy’s family realized that he probably wouldn’t be able to enjoy one more Christmas. So they decided to celebrate early, putting up a tree and decorations, and their Ohio neighborhood followed suit.

“In his mind it is just Christmas,” said McKenzie Allen, 21, Brody’s sister. “He woke up one day and the Christmas tree was out. He doesn’t know it isn’t really Christmas. He is just enjoying it.”

Brody’s health has deteriorated so that he no longer has the energy of a toddler or the use of his left arm and left leg. He likes to be outside, so he often sits in a red Radio Flyer wagon, a blanket thrown over him and a hoodie pulled over his head, while his siblings pull him around their neighborhood in Colerain Township, a suburb of Cincinnati.
