The first volumes were much criticized because they were considered unsuitable for children, both for the scholarly information included and the subject matter. Many changes through the editions – such as turning the wicked mother of the first edition in "Snow White" and "Hansel and Gretel" to a stepmother, were probably made with an eye to such criticism. They removed sexual references—such as Rapunzel's innocently asking why her dress was getting tight around her belly, and thus naïvely revealing her pregnancy and the prince's visits to her stepmother—but, in many respects, violence, particularly when punishing villains, was increased. In 1825, the Grimms published their "Kleine Ausgabe" or "small edition," a selection of 50 tales designed for child readers. This children's version went through ten editions between 1825 and 1858.
