More than 1,200 Christmas cards are arriving each day at a tiny post office in a small rural Utah town in a campaign to help make a dying girl's last Christmas special.

Tami Fausett says her 6-year-old daughter, Addie Fausett, stopped growing when she was 3. Her undiagnosed illness is causing cerebral atrophy. Doctors say she has less than one year to live.

Her grandmother started a social media push last month asking people to send Addie Christmas cards to make sure she knows she's loved. She lives in Fountain Green, Utah, about 100 miles south of Salt Lake City.

The cards have come from Germany, Australia and Saudi Arabia. One judge sent a signed and stamped court order for Addie to have a Merry Christmas.
