A man left a baby with brain damage and “extensive” bleeding after violently shaking it.
Joshua Bagshaw, 24, from Stoke-on-Trent, Staffordshire, told emergency services the child was having “a spasm” and a twitch on side of its body after the incident.
Doctors found haemorrhaging and swelling to the brain after the tot was rushed to Royal Stoke University Hospital
At Alder Hey Children's hospital in Liverpool, “extensive bleeding” was detected, Stoke-on-Trent Live reports.
However, Bagshaw has since been spared jail.
Prosecutor Andrew Smith QC told Stoke-on-Trent Crown Court that "a doctor concluded the likely cause was from suffering a recent head injury or by forcible shaking".
Bagshaw, from the village of Abbey Hulton in Staffordshire, pleaded guilty to two counts of grievous bodily harm on the basis that he did not intend to cause injury.
Mr Smith added: "By his pleas of guilty he accepts the injuries were inflicted by him. The injuries were caused in two shaking-type events."
Barry White, mitigating, said: "He is genuinely remorseful. He is quite affected by everything that happened."
The suspended sentence includes a 30-day rehabilitation activity requirement and 180 hours of unpaid work.
Judge David Fletcher said: "The child had undergone some damage to its brain on at least two separate occasions.
"There was shaking of the child. That is the best way of describing what occurred. You accept it was your behaviour that caused the injuries."
The court heard the child had largely recovered from its injuries, but it is not known if they will lead to any long-term health problems.
Bagshaw must also pay £500 in costs.
