Sinead O'Connor - Scorn Not His Simplicity

This is a cover, bit I prefer it to the original artist. Knowing the backstory makes the song physically hurt I reckon.

From Wiki:

"Scorn Not His Simplicity" is a song written by the Irish musician and songwriter Phil Coulter

Phil Coulter's first son was born with Down syndrome, and several months later the father wrote the song "Scorn Not His Simplicity" about his experiences with his son's disorder.
