Although no cure has yet been developed for childhood imagination, preventative measures can deter children from potentially hazardous bouts of make-believe.

“Many of the suggestions are really quite simple, like breaking down cardboard boxes or sewing cushions to couches so they cannot be converted into forts or playhouses,” McMillan said. “Blank pieces of paper, which can inspire non-reality-based drawings, should be discarded unless they are used in one of our recommended diagonal folding and unfolding activities. And all loose sticks left lying in the yard should be carefully labeled ‘Not a Sword.'”

Unfortunately, removing everything from a child’s field of view that could stimulate his active young mind is extremely time-consuming, and infeasible as a long-term solution, McMillan acknowledges. “To truly protect your children, you must go to great lengths to completely eliminate their curiosity, crush their spirit of amazement, and eradicate their childlike glee. Watch for the danger signs: faraway expressions, giggle fits, and a general air of carefree contentment.”

Added McMillan: “Remember, if you see a single sparkle of excitement in their eyes, you haven’t done enough.”
