I don't think so. The Child ballads are so called because they were collected by Francis J. Child (1825-1896), not because they were intended for children.

A quick search on abebooks.com, turned up a number of late 19th and early 20th century versions of Shakespeare with titles such as "Children's Shakespeare" and "Tales from Shakespeare for Children" by various authors and editors, all of whom simplified and expurgated the plays to a greater or lesser degree to make them suitable for the delicate ears of children. The best known is probably Charles & Mary Lamb's "Tales from Shakespeare for Children" which translated the plays into prose stories -- and naturally leaving out the naughty bits.
