Posthumous sequels

An authorised sequel Return to the Hundred Acre Wood was published on 5 October 2009. The author, David Benedictus, has developed, but not changed, Milne's characterisations. The illustrations, by Mark Burgess, are in the style of Shepard.

Another authorised sequel, Winnie-the-Pooh: The Best Bear in All the World, was published by Egmont in 2016. The sequel consists of four short stories by four leading children's authors, Kate Saunders, Brian Sibley, Paul Bright, and Jeanne Willis. Illustrations are by Mark Burgess. The Best Bear in All The World sees the introduction of a new character, Penguin, which was inspired by a long-lost photograph of Milne and his son Christopher with a toy penguin.

In 2016, Winnie-the-Pooh Meets the Queen was published to mark the 90th anniversary of Milne's creation and the 90th birthday of Queen Elizabeth II. It sees Pooh meet the Queen at Buckingham Palace.

In 2021, marking a century since Milne bought the stuffed toy from Harrods department store for his son Christopher Robin that would inspire Milne to create the character, Winnie-the-Pooh: Once There Was a Bear, the first prequel to Milne's books and poetry about the bear, was authorised by the estates of Milne and Shepard. Inspired by the real life of Christopher Robin, it is written by children's writer Jane Riordan in the style of Milne, with illustrations by Mark Burgess emulating the drawings of Shepard. It sees Winnie-the-Pooh exploring Harrods as well as visit London's Natural History Museum and London Zoo, before leaving London and going back to the Hundred Acre Wood.
