Prince Harry was once close to his nephews both geographically and mentally. The British tabloid The Sun found out that he gave Prince Louis his christening gift in 2018.
“One of Harry's happiest childhood memories is his mother reading books at night. And if William’s favorite book was “Robinson Crusoe,” then Harry loved the works of Alan A. Milne, said an unnamed friend of the prince. “She (Princess Diana) loved all the good old classics, so Harry had the brilliant idea to start collecting sort of a little library of first editions for Louis, Charlotte and George to enjoy when they were older.” He initially wanted to give Lewis Carroll's Alice Through the Looking Glass, which sold for £24,000, but decided that Winnie the Pooh would be a better fit for the first volume."
As a result, Prince Harry purchased the first edition of the book by A.A. from London collector Peter Harrington as a gift to Louis. Milne 1926 for £8,000. True, according to acquaintances of the royal family, the Welsh do not allow their children to read rare books on their own to avoid damage, but do it all together.
