 This study found that taking photos of babies' sleep environments can be used as a reliable method of assessing sleep safety. The researchers found that the photos taken by the mothers correlated well with observations made by both expert and novice coders, indicating that this method could be used to accurately measure sleep safety. Additionally, the photos showed that most parents put their babies to sleep on their backs, which is important because it reduces the risk of sudden unexpected infant death.
