Prince William has said Prince George's first day at prep school went smoothly after he was forced to carry out parenting duties alone.
William's wife Kate had hoped to join him on the school run, but was suffering from severe morning sickness with her third pregnancy and was too ill to attend.
William drove four-year-old George to Thomas' Battersea, a fee-paying independent school in south London, at 8.45am.
The youngster, who will be known as George Cambridge to his classmates, was helped out of the car by his father after being driven inside the school gates.
"There was one parent who had more of an issue with their children - so I was quite pleased I wasn't the one," said William.
George - who was wearing a light-blue shirt, a navy V-neck pullover, shorts and black shoes - looked tentative and clutched his father's hand as he was led towards the school entrance.
He shook hands with Helen Haslem, head of the lower school.
Then, with William holding one hand and Ms Haslem the other, he walked inside.
Ben Thomas, who is principal of Thomas's London Day Schools and was headmaster of Thomas' Battersea for 18 years, said he hoped the future king would learn to "be himself".
"The whole aim of these precious early years of education is to give children that confidence in who they are," he said.
"So we are not going to try to mould him into any kind of particular person."
The school, where fees cost from €19,000 a year, has been described by the Good Schools Guide as "a big, busy, slightly chaotic school for cosmopolitan parents who want their children to have the best English education money can buy".
It is understood William and Kate will try to do the school run as often as possible.
