It's important that children grow up in a home environment in which adult interactions support their natural desire to play in this way. Research has shown that pretend play is more common among children whose parents talk to them often, read or tell bedtime stories, and explain things about nature or social issues to them. Research has also found that in schools, encouraging pretend games either in the curriculum or at recess can enhance imaginations and curiosity.
