A JUDGE told a man who slapped a child and then tried to pass the injury off as a rash that there would be "outcry" if he was not jailed.
James Knaggs, 24, was convicted by a jury of assault occasioning actual bodily harm following a three-day trial.
The one-year-old, who cannot be named for legal reasons, suffered bruising to the entire side of his face in the July attack.
Prosecutor Angela Wrottesley told Hull Crown Court that when the bruise appeared on the child's face, Knaggs claimed it was a rash, which delayed the time it took for the child to receive treatment.
Throughout the trial, Knaggs, of Roundhay Road, Bridlington, denied ever striking the child.
However, the trial heard the child had been subjected to a "full hand" slap across the side of his face.
Sentencing Knaggs to two years, Recorder David Smith told him: "Let me tell you, having listened to the evidence, I do agree with the verdict.
"There was only one serious culprit for infliction of this harm and that was you.
"You didn't have then the presence of mind to admit to it and you didn't have the presence of mind to admit to it in police interview.
"There would be outcry if I didn't send you to prison immediately."
Stephen Robinson, defending, argued the assault was at a lower end of the scale, but Recorder Smith said Knaggs' attempt to cover-up his crime and his failure to get immediate medical attention for the victim were aggravating factors in the case.
Mr Robinson asked the court if it would consider offering his client a course to equip him with skills necessary to change the error of his ways.
He said: "He is still a young man. Perhaps an immature young man who could do with some help in acting properly, particularly in regards to children."
However, Recorder Smith dismissed the request.
He said: "It is primitive behaviour."
Addressing Knaggs, who was supported in court by family and friends, Recorder Smith said: "In terms of mitigation, there is very little.
"You have no previous convictions. You are of previous good character and that is about as much as you have going for you.
"You blamed the injury on a mark when you knew full well that you had brought about that by a slap, a full hand across the side of his face and then attempted to play it down, delaying medical attention, which could have made it worse."
In addition to his prison sentence, Knaggs was ordered to pay a £100 victim surcharge.
