Adam Andrews violently attacked the 21-day-old tot, who now requires round-the-clock care.
The 37-year-old has been jailed for three years after being convicted of grievous bodily harm without intent.
Ipswich Crown Court heard how the boy was a victim of “violent shaking” in June 2018, East Anglian Daily Times reports.
His mum told the court how he is now blind and paralysed, will never walk or talk and requires 24-hour care.
She said: “His bedroom is not filled with toys but with feed machines and medical equipment.
“He will never be able to have food or water and has to be fed by a button attached to his bowel.”
The mum also revealed her son suffers between 30 and 40 seizures a day as a result of the attack.
She added: “I have to watch my child deteriorate for what this man has done in a burst of outrage of anger. He should not be allowed to walk the streets while I care for my child around the clock.
“I have to accept it’s very likely I’m going to outlive my child.
“When I fall asleep every night my biggest fear is [he] will not wake up with me.”
The court was told the shaking likely happened over a few seconds and was a “spontaneous loss of control”.
Andrews has shown “no remorse” since the horror, it was said.
The thug, of Great Whelnetham, near Bury St Edmunds, was cleared of a more serious charge of inflicting grievous bodily harm with intent.
Sentencing, Judge David Pugh said: “Precisely what happened later that night and why, only you will know.”
