Physiological Effects of Cosleeping with Infants

when they are more used to sleeping alone, sleep differently when with when they are more used to sleeping alone, sleep differently when with their mothers. The babies seem to spend a greater percentage of their sleep time in levels 1-2 and less time at the deeper levels, exhibit more REM sleep, and are awake longer. In other words, they are more often moving among sleep levels, and they sleep lighter. Christopher Richard, Mosko, and McKenna have also found that most co-sleeping pairs spend ...

 Sleeping Arangements Across Climates

The study, published in the October issue of...
