Anastasia from Niagara Falls is like many little girls: she loves Christmas songs. But she is far from an ordinary child. She was diagnosed with an aggressive brain tumor that caused her to go completely blind, making music one of her main joys. Ana knows when the holiday season is approaching and begins singing Christmas carols in October, before they are even being played on the radio.

Anastasia was diagnosed in the summer of 2016. She has lost her ability to walk and see, and has faced about 15 surgeries in only three years. Last week on Monday, Ana's mother, Lene'e Gray, was told her daughter wouldn't live through the day. It wasn’t the first time the family heard that prognosis — and it wasn't the first time Ana has proven it wrong.

"You would have never have known that they said Monday might have been her last day. She is the one who gives us hope. Not the doctors. Not anything else," said Gray.

When police officers and firefighters heard Ana wanted them to sing her Christmas songs, they were touched and made her wish a reality.

"I saw her on Facebook on her Facebook page a couple of years ago. I was pregnant with my daughter around the same age. I learned about her illness and she has had a special place in my heart ever since," said Detective Sandi Arist.

"We reached out to her mom. Unfortunately, she wasn't in the area for us to see her personally, but Jingle Bells is her favorite song, so she asked if we could videotape it. We got a hold of some guys, made some phone calls," said Detective Patrick Clifton.
