Growing up as part of the Cambridge family, the new royal baby will be one of the most famous youngsters in the world but the Duke and Duchess of Cambridge work hard to make sure their children have as much of a normal life as possible.
The prince's milestones - leaving hospital after being born, his christening and his first public engagement - will be covered in minute detail by the media.
But for the most part, his early years will be spent happily away from the cameras with William and Kate previously releasing photos of their children at key moments to encourage the press to avoid using paparazzi shots.
So what will the royal baby's childhood be like?
The prince's main home in London will be Kensington Palace's Apartment 1A, which used to belong to Princess Margaret.
It was refurbished at a cost of STG4.5 million ($A8.8 million) to the taxpayer and with a big, private walled garden, there is plenty of space to play outside, as well as some 20 rooms to explore.
The baby's nursery may well feature some Ikea furniture with William and Kate revealing they turned to the popular Swedish firm for Prince George and Princess Charlotte's rooms.
The royal couple also have a 10-bedroom Georgian Grade II listed house - Anmer Hall on the Queen's Sandringham Estate - in Norfolk.
At the age of two, the little prince will start nursery.
Charlotte already attends Willcocks Nursery School - a short distance from Kensington Palace - which charges fees of just over STG3,000 a term.
The school has been described in reports as having a loyal following of "old English families and chic foreigners".
He will then probably follow George to his private school Thomas's Battersea - which Charlotte is expected to attend as well.
Fees at the south London school cost more than STG17,600 a year.
The school's most important rule is "Be kind" and it expects its pupils "not just to tolerate but to celebrate difference, including faith, beliefs and culture".
William boarded at Eton, while Kate was a part-time boarder at Marlborough College - but it is not yet known whether their children will go to boarding school.
Kate has previously been vocal about the importance of mental health and opened up about how she wants to raise her children, saying qualities such as kindness were just as important as academic or sporting success.
"My parents taught me about the importance of qualities like kindness, respect and honesty, and I realise how central values like these have been to me throughout my life," she once said.
She and William have spoken often about the importance of talking about mental health.
"Everybody has mental health and we shouldn't be ashamed of it and just having a conversation with a friend or family member can really make such a difference," the duke said.
Nanny and other staff
George and Charlotte's full-time live-in nanny is Spanish-born Maria Teresa Turrion Borrallo, who trained at the prestigious Norland College.
Royal protection officers will always be close by, but hands-on parents the duke and duchess will strive to make up for the lack of freedom that royal childhoods can sometimes provide.
