At age 2-3 years, my son has enjoyed lifting the flaps on this charming book, but a few minor issues bother me as we read it. First, the trick-or-treaters say, "Trick-or-treat for Unicef!" Nothing against Unicef, but after the first couple of times reading this aloud, it struck me as odd and I decided to leave it at "Trick-or-treat." Unfortunately my son had already memorized the Unicef part and "corrects" me as we read. Second, at Corduroy's Halloween party everyone bobs for apples. Ewwww! Does anyone do that anymore? Finally, at the store Corduroy buys "everything he needs for his costume," but later we see his costume is the classic ghost: a sheet with eye holes. What exactly did he buy for *that*? Admittedly these are nitpicky points, however, and overall the book is an enjoyable intro to Halloween.
