Children's sleep difficulties: Reports differ from children to parents

A new study published in Child Development found that children report more frequent sleep problems than their parents acknowledge. The researchers suggest that genetic and environmental influences play a role in most sleep problems. Parents may be unaware of night waking or delayed sleeping patterns, leading to overestimation by children.
