Good work Caseysmom. I can only echo this from the site you found.

Terri is not in a coma.
She is not on life support.
She laughs, cries, vocalizes.
Her face brightens for her mother.
She swallows.

”So why don't they let her mother feed her?”

The husband/guardian doesn't allow.
His lawyers don't allow.
The judge & courts do not allow.
