The controversy about what constitutes safe and nurturant infant sleep environments.

In 1999, the U.S. Consumer Product Safety Commission stated that cribs provide the safest sleep environment for infants. Scientific data fails to support that statement and controversy continues in the scientific, medical, and parenting communities. Recent data demonstrate that cribs may represent the most unsafe sleep. This article seeks to inform health care professionals of the issues involved in the controversy and to offer guidelines for educating parents about safe and unsafe sleep practices.
