"He had to watch it twice," Murray told the Chronicle. "I don't even know the man's name, but I think it's really sweet that he thought of (Aiden) for Christmas."
Luera shared a photo taken from the Ring camera footage Tuesday on Facebook.
"All is not lost in this world and in my profession, I don't see a lot of acts of kindness like this," he wrote. "I want to wish this man and his family a Merry Christmas. Thank you for the gift you left my little one. May god bless you."
Murray told the Chronicle she and Aiden plan to make Christmas cookies to give to the garbage man Friday to thank him for his thoughtfulness.
"It meant a lot to us, this very small act of kindness," Murray told KTRK-TV. "It just meant the world."
