Society's Child
Tony Barnes, 30, had 63 pornographic pictures of children and hundreds of babies and young girls in nappies on his laptop, a court heard.
He was arrested in 2009 after his boss - a mother-of-three from Winnipeg in Manitoba, Canada - tried to close his laptop and found the sexually explicit pictures on his laptop.
Police searched his room after obtaining a warrant and found an 'abundance of diapers', including a dirty one under a pillow, Terry McComb, prosecuting, said.
They also found the pictures of children and a series of online chats in which he freely discussed sexually abusing children, often using soiled nappies.
He was hired five months before by the parents through Nannies International, which provided 'glowing work references', Mr McComb said.
'The family just thought he was golden - they thought he was great,' he added.

A protester waves an Egyptian flag on top of a tank during celebrations in Liberation Square in Cairo today.
The army sought to stave off pressure from jubilant protesters to swiftly hand power to a civilian-led administration by saying that it is committed to a "free democratic state".
The military leadership gave no timetable for the political transition, and many of the demonstrators who filled Cairo's Tahrir square for 18 days rejected the military's appeal to dismantle the barricades and go home.
They said they were waiting for specific commitments from the military on their demand for a civilian-controlled interim administration, the lifting of the oppressive state of emergency and other steps toward political liberalisation.
Islamabad - A Pakistani court issued an arrest warrant for ousted military leader Pervez Musharraf on Saturday over allegations he played a role in the 2007 assassination of an ex-prime minister and rival. It was a major setback for the onetime U.S. ally, who was plotting a political comeback from outside the country.
Musharraf, who has not been charged, described accusations that he had a hand in the attack on ex-Prime Minister Benazir Bhutto as a smear campaign by a government led by her aggrieved husband.
The stunning allegation that Musharraf - a self-declared opponent of Islamic militancy - was linked to extremists accused in the attack was likely to keep him out of Pakistan, at least in the short term.
His possible arrest abroad did not appear imminent, but Pakistan's information minister, Firdous Ashiq, Awan said the government will contact Interpol about seeking Musharraf's detention if the court requests it.
Musharraf's spokesman said the former leader was in Dubai, with no plans to go to Pakistan. Speaking from London, where Musharraf has lived in self-imposed exile, Fawad Chaudri quoted him as saying that the accusations were "absurd and ridiculous."
Afghan officials say 15 of the victims are police officers as the attacks mainly targeted the police headquarters. Forty-five people have been injured in the attacks.
One intelligence agent is also reported to have been killed in Kandahar Province.
The provincial governor says a number of militants armed with guns and grenades were involved in the attacks.
The Taliban have claimed responsibility for the attack.
Violence has been at its worst in Afghanistan since the US-led invasion in 2001.
The Afghan interior ministry has declared 2010 the deadliest year for civilians since the US-led invasion of the country in 2001. The ministry's spokesman said more than 2,000 civilians lost their lives in violence across Afghanistan.
Hours before Mubarak announced his resignation, government vigilantes clashed with pro-democracy protesters who surrounded a police station in the Egyptian city of El-Arish late Friday to free prisoners held by the regime, a Press TV correspondent reported.
Government forces then fired tear gas and live bullets to break up the demonstrators, killing at least 10 protesters and injuring 50 others.
Protesters, who were increasingly incensed by Mubarak's refusal to cede power in his televised speech a day earlier, eventually managed to secure the release of their friends and relatives during the melee, while twelve police officers surrendered to the crowd.

The Saturday rally, which was approximately attended by 4,000, saw demonstrators chanting, "After Mubarak, it's Ali's turn," AFP reported.
"Get out, Get out Ali" and "The people want the regime to fall," some shouted.
Yielding knives and batons, hundreds of Saleh's supporters, attacked the protesters, injuring at least two of them, DPA said.
Mubarak handed power over to the Supreme Council of the Egyptian Armed Forces on Friday, giving in to 18 straight days of pro-democracy protests.
- 400 arrested as officers enforce no-protest ban in Algiers
- Up to 5,000 protesters rally in Yemeni capital of Sana'a
- Arab leaders make concessions to avoid repeat of Egypt
Demonstrations in Algiers quickly turned to running clashes with police who had been ordered by the government of President Abdelaziz Bouteflika to enforce a no-protest ban. Police took up positions throughout the centre of the city hours after the tumultuous scenes in Cairo, which are likely to have significant ramifications across the region.
Even before Egypt's Hosni Mubarak had stepped down, the 12-year regime of Bouteflika had been considered to be under most threat from the popular uprisings now galvanising the Arab states. Wedged alongside Tunisia, where President Zine al-Abidine Ben Ali was rolled 30 days ago, and near Egypt, which fell on Friday, the unstable nation has many of the characteristics of both - a disenfranchised youth and rising prices of basic goods, such as sugar and cooking oil.
The Vatican has ousted three men from the priesthood years after they were accused in sex , the Archdiocese of Boston said yesterday.
"These men are no longer to function, or present themselves as priests, with the exception of offering absolution to the dying," said archdiocese spokeswoman Kelly Lynch.
In 2002, Frederick J. Cartier was accused of sexually abusing a minor in the early 1970s. By the time the allegation was received, Cartier had been out of ministry for more than 20 years, the archdiocese said.
