The birth of a child is a happy event for the family. According to traditional beliefs, however, confinement and childbirth expose the family, and especially the mother and the child to harm from the spirit world. A woman who dies in childbirth—crosses the river (chhlong tonle) in Khmer is believed to become an evil spirit.[clarification needed] In traditional Khmer society, a pregnant woman respects a number of food taboos and avoids certain situations. These traditions remain in practice in rural Cambodia, but they have become weakened in urban areas.
