We have very sad news to report. Avery Canahuati, the five-month-old who inspired the 'Avery's Bucket List' blog, died Monday.

Last month, Avery was diagnosised with spinal muscular atrophy, and given 18 months to live. In an effort to make her short life as enjoyable as possible, her parents, Mike and Laura Canahuati, made a bucket list for their daughter which included activities such as "play with a pinwheel" and "get picked up by a fireman." The list went viral, as many were touched by Avery's story.

Sadly, Avery won't get to complete many of the items on the list.

Avery's passing this quickly came as a complete shock to all of us, as she had just been given a thumbs up at her last doctor's appointment only three days ago," Mike Canahauati wrote in his blog. "While we were aware of the severity of her diagnosis, we never lost hope for Avery."

Mike and Laura will continue to raise awareness for spinal muscular atrophy, which is the number one killer of children under two.

"Before Avery passed away, I made her a promise that I would continue to be an activist in raising SMA awareness, making genetic testing universally available, and in finding a cure for her friends," Mike Canahauti wrote. "I will not break that promise and in the name of SMA awareness and funding a cure, I hope parents of children everywhere will look at 'Avery's Bucket List' and help her complete items she was unable to."
