From: Postural change for supine position does not disturb toddlers’ nap
Representative daily activity-rest patterns of toddlers between 1 and 2 years of age during naps. The arrows indicate nap onset and end time, respectively. (a) After the toddler had transient wake #1 during nap, she had small body positioning changes within the supine position range and soon returned to sleep. After she had transient wake #2, she changed her body position from supine to lateral but soon returned to supine herself and went back to sleep smoothly. (b) After the toddler had transient wake #3 during nap, he changed his body position from supine to prone, leading to a forced postural change from prone to supine by a nursery staff member. Please note that he returned to sleep without any wake bout after the postural change. When he had another transient wake (wake #4), he again changed his body position from supine to prone and a nursery staff member returned his body position from prone to supine. However, he again changed his body position from supine to lateral and finally returned to supine himself and went back to sleep smoothly.
