When arranging their child's next play date, American parents may want to ask if there are any unlocked guns in the prospective playmate's home.

The reason: almost 2 million American homes with kids contain unlocked, loaded guns, experts say, and dozens of kids die each year from unintentional shootings.

That's why the Center to Prevent Youth Violence (PAX) has joined forces with the American Academy of Pediatrics (AAP) to designate June 21 "National ASK Day."

The goal is to protect children from accidental shooting injuries or even death by encouraging parents to find out whether or not guns are present in homes where their kids play.

Home learning experiences such as reading books with parents can improve low-income preschool children's readiness to start school, researchers say.

The new study included more than 1,850 U.S. children and their mothers in families with household incomes at or below the federal poverty line. During home visits when the children were ages 1, 2, 3 and 5 years, the New York University researchers looked at how often the children took part in literary activities (such as shared book reading), the quality of the mothers' interactions with their children (such as exposing children to frequent and varied adult speech), and the availability of learning materials, including children's books.
