Many parents, teachers and child-care providers are troubled with aggressive play.
Adults make most of the decisions, and older siblings and playmates make up most of the rules.

Preschoolers may feel a bit lost in this world of older decision makers. A new vocabulary. These types of play make it possible for preschoolers to do some sorting by making distinctions between good and evil, right and wrong, power and powerlessness, good guys and bad guys, acceptable and unacceptable behaviors. The glamour, power and wit of superheroes and good guys are attractive to young children who feel they have few of these qualities.
