Milne's second book of children's poetry: “We have been nearly three years writing this book. We began it when we were very young ... and now we are six. So, of course, bits of it seem rather baby-ish to us, almost as if they had slipped out of some other book by mistake. On page whatever-it-is there is a thing which is simply three-ish, and when we read it to ourselves just now we said, "Well, well, well," and turned over rather quickly. So we want you to know that the name of the book doesn't mean that this is us being six all the time, but that it is about as far as we've got at present, and we half think of stopping there. P.S.—Pooh wants us to say that he thought it was a different book; and he hopes you won't mind, but he walked through it one day, looking for his friend Piglet, and sat down on some of the pages by mistake.” From the Introduction. - Summary by A.
