Just as Sarah Coglianese's daughter, Scarlett, was learning to walk, Coglianese started to fall. Eventually, she was diagnosed with ALS. Click through the gallery to see more photos of Coglianese and her family.
Coglianese married her husband, Rob, on September 19, 2008.
Seen here together on Christmas Eve in 2009, Coglianese and her husband were thrilled to become parents. She had a normal, healthy pregnancy.
On Christmas Eve the next year, they were thrilled to be holding baby Scarlett. Coglianese's ALS symptoms had not yet appeared.
In August 2011, Coglianese was still undiagnosed, but began to fall for no reason, it seemed. Here, she and her daughter carefully navigate the stairs at her uncle's lake house.
By January 2014, Coglianese had been officially diagnosed with ALS and was using a wheelchair. This photo was taken on Scarlett's first day of her final year of preschool.
