Tummy Time

According to wikipedia Tummy time is a colloquialism used to encourage parents to ensure that their infant children spend time in the prone position while awake and supervised. Placing infants on their stomachs while they are awake has been recommended to offset the motor skills delays associated with the back sleep position but positioning the infant on their stomach while awake will not impact the amount of slow wave sleep since tummy time only occurs when an infant is awake.
