The man, 32, previously pleaded guilty to charges of sexual interference and making and possessing child pornography. He cannot be identified due to a publication ban.
He was caught in August 2010 after the sister with whom he once lived stumbled across two alarming images on a computer showing her sleeping newborn son's right hand placed on her brother's partially erect penis.
According to the Crown attorney, the man failed to realize his iPhone was backing up images to his computer. The sister immediately called police when she saw the material.
The man instantly confessed to cops checking out her complaint.
"I'm sorry," he was reported as saying. "I'm so ashamed, I don't know why I did this."
He told investigators he took the photos for his own gratification, Crown attorney Terry McComb said. He also expressed gratitude to them at being caught.
A police search of the computer found 38 unique child abuse images, 15 of them of the baby -- four showing him putting his penis on the child's groin.
The rest of the pictures were of girls in the range of 4-12 years old. Police also found 127 graphic child abuse videos, along with a large mix of legal adult pornography.
An in-depth psychological report stated the man was an Internet and porn addict, spending upward of eight hours a night surfing the 'net -- roughly half of that time spent searching out porn.
He told the examining psychiatrist he took the pictures of his nephew "for a lark," McComb said, leading the doctor to conclude he suffers "cognitive distortions" when under emotional stress.
The man apologized to Judge Ted Lismer for his actions and mentioned the psychological harm he's caused his sister.
"I know that what I've done is going to affect her for the rest of her life. I'm looking forward to getting the help I know I need," the man said.
Court heard he will take sex-offender treatment while in custody.
Lismer also placed him on three years of supervised probation, which includes a provision for warrantless searches of his home when he's released.
He's also barred for the next decade from attending parks, playgrounds, daycares and schools where kids under 16 may be.
