Nathan Rawling denies causing baby's injuries
A 36-year-old man has denied leaving a one-month old boy with life-threatening injuries after a "frenzied, brutal and persistent assault".
Nathan Rawling, from Gravesend, told Maidstone Crown Court the baby's mother was responsible for the attack in December 2011.
The child's injuries included 26 rib fractures, a broken arm, a broken collar bone, and two punctured lungs.
Mr Rawling has denied the charge of grievous bodily harm with intent.
He is accused of carrying out the attack after the baby urinated on him.
On Wednesday, John O'Higgins, for the prosecution, asked him: "Something happened to trigger some kind of murderous rage in you. What was it?"
Mr Rawling, of St Gregory's Crescent, replied: "I haven't lied. I have told the truth.
"I haven't had any outbursts through anger or rage."
Mr O'Higgins then asked: "Is that when you put your hand on his chest and squeezed as hard as you could, and you almost squeezed the life out of him?"
Mr Rawling replied: "No."
The trial has heard how Mr Rawling told police officers the baby stopped breathing and the injuries were caused by his attempts to resuscitate him.
The trial continues.
