From Cas’ Mother:

Cas was a beautiful, happy boy.  He had beautiful eyes and hair and a beautiful smile.  Everyone fell in love with him. Cas was born on October 26th, 2019  and he became a butterfly on November 12th, 2020. During his brief life, Cas had few complaints.  He was going to be tube-fed, but shortly after his first birthday, he became very congested and stuffy. He appeared to have swelling in the airways, which caused him very serious problems.  Shortly after these respiratory complications, he died in his sleep in our arms in hospital.
