Nathan Pick, 38, from Chaddesden in Derby is starting a seven year jail sentence after lashing out at his disabled son and killing him. The baby, who was born with a heart defect and had to be tube-fed, suffered brain injuries and died in hospital as a result of the blow to the back of the head.
Sentencing Pick, Lord Justice Julian Flaux said he accepted Pick had not set out to kill or seriously harm his child but that his son could not be blamed for crying. He also accepted Pick, who has a 12-year-old son, was not a violent or bad man.
"The stress caused you to snap. You did not intend to kill him or cause him serious injuries but you now accept that blow was an unlawful act."
Tragically the baby was the second child his mother had lost in three years.
Her daughter Zoe died of sudden infant death syndrome in 2009 when she was seven weeks old. There were no suspicious circumstances.
