The Guinness world record for the Most Christmas Cards received was set 20 years ago by Jarrod Booth, a Canadian who received 205,120 cards.
Guinness World Records also recognized the world record for the largest collection of Pokémon memorabilia; it belongs to Lisa Courtney (UK), with 14,410 different items.
On Christmas Eve alone, Dalton's mom, Jessica Dingus, said he received between 40,000 and 50,000 cards. The post office in Campton had to make two truck deliveries.
Postal workers in Magoffin County, Ky. created a giant post card and hand-delivered it to Dalton Dingus.
The post card delivered by the postal workers is 4 feet tall and 8 feet long. It weighs 46 pounds and officials think it could be the largest card ever. Postal workers said they paid $90 for the card's postage fee.
Now the cards are going to Dalton's grandpa's church, the Bethlehem Calvary Church in Salyersville, where they are sorted and counted by hand. The special visits and deliveries, including a giant card from the Post Office, which Dalton's mom said he really loved, have made the season bright.
Dalton takes 18 different medicines every day, "lots of pills and antibiotics," his mother says.
He goes through 12 liters of oxygen a day and wears a face mask to help him breathe, making him look like a miniature fighter pilot with an interest in coloring and playing with Lego blocks.
"Dalton has been doing really well the past three weeks. He is still very weak but improving," Jessica said. "The cards give him something to look forward to. Something to get excited about," she said. "The prayers are working."
"But prayers aren't enough for the sticklers at Guinness World Records," the ABC News reported. Despite some reports that Dingus had already broken the record for receiving the most Christmas cards, spokeswoman Jamie Panas said Guinness World Records "currently does not monitor a category for this."
