Prince Harry has spent £8,000 ($10,628) on a first edition Winnie The Pooh as a gift for his nephew Louis' christening today.
The 11-week-old, who is fifth in line to the throne, will be baptised by the Archbishop of Canterbury, the Most Reverend Justin Welby, in the Chapel Royal at St James's Palace.
It will be a private ceremony with close friends and family invited only. Prince George, four, and three-year-old PrincHe is understood to have made the purchase from rare book seller Peter Harrington in Kensington, London.
A friend told the newspaper: 'One of Harry's happiest childhood memories was being read a bedtime story by his mother.
'She loved all the classics and Harry had the brilliant idea of starting a little library of first editions.'
It is thought the newlywed originally considered buying Lewis Carroll's Through the Looking Glass, priced at £24,000 ($31,885) but decided Winnie the Pooh would be more suitable.
The same friend told The Sun Prince Harry was a big fan of books as a youngster, devouring anything A.A. Milne but his favourite was Robinson Crusoe.
It will be the first time the Duke and Duchess of Cambridge and their three children have been seen together as a family of five.
Kensington Palace has yet to release the guest list, but royal christenings are usually a small, family affair.
Newlyweds the Duke and Duchess of Sussex are likely to put in an appearance, as are Kate's pregnant sister Pippa Matthews, and her brother James Middleton.
Meghan was christened and confirmed in the Chapel Royal by the Archbishop, who also married the Suits star and Harry at Windsor in May.
Louis' godparents, who will be announced on the day, will take part in the private 40-minute traditional religious ceremony, which begins at 4pm in the intimate, oak-panelled chapel.
There is speculation the Cambridges, who usually opt for close friends and confidantes, may choose William's trusted private secretary Miguel Head, who is leaving the post this month, to be a godfather.
They might even turn to one of William's cousins, Peter Phillips, Princess Beatrice, Princess Eugenie or Lady Louise Mountbatten-Windsor – a move which would delight the Queen.
The baby prince – Louis Arthur Charles – was born in the private Lindo Wing of St Mary's Hospital in Paddington, London, on April 23 – St George's Day – weighing 8lb 7oz.
He will be welcomed into the Christian faith dressed in the same frilly, cream gown used for George and Charlotte.
The robe is a replica of the intricate lace and satin dress made for Queen Victoria's eldest daughter in 1841.
George was also christened in the Chapel Royal, but Charlotte was baptised at the Church of St Mary Magdalene in Sandringham.
After George's christening in 2013, the Prince of Wales and the Duchess of Cornwall gave a private tea at nearby Clarence House, and guests were served slices of christening cake, taken from a tier of William and Kate's wedding cake.
