Prince Harry is reportedly keen to build up a library for his nephews Prince George, 4, and Prince Louis, as well as niece Princess Charlotte, 3, in memory of his late mother, Princess Diana.
A source told The Sun, 'One of Harry’s happiest childhood memories was being read a bedtime story by his mother.
'She loved all the old classics and Harry had the brilliant idea of starting a little library of first editions for Louis, Charlotte and George to enjoy as they get older.'
According to the insider, Harry originally planned on buying a copy of Lewis Carrol’s Through The Looking Glass for Prince Louis, which would have cost a whopping $42,600, but decided Winnie-the-Pooh was more appropriate.
Prince Harry and his new wife Meghan Markle, 36, were among just 30 guests invited to Louis’ christening.
