This study was conducted to compare the effectiveness of three stair positioning pillows and positioning materials on the sleep-wakefulness status of preterm infants.

It is known that newborns have similar brain activity in the intrauterine period and REM sleep activity, and they sleep more than adults and spend most of their sleep in the REM sleep period. Therefore, sleep quality in the newborn period is directly related to healthy development. Providing a developmentally supportive position in neonatal intensive care units (NICU) is necessary not only for neuromotor and musculoskeletal development, but also for physiological function and stability, thermal regulation, bone density, neurobehavioral organization, calmness and comfort, skin integrity, optimal musculoskeletal development, facilitation of sleep, growth and brain development. Excessive noise in the NICU, prolonged bright lights, separation from the mother, frequent invasive procedures and pain experience are among the factors that disrupt, shorten and create stress in the sleep duration of preterm babies. It is very important to support the sleep of preterm babies in the NICU in order to improve their growth and development, especially their brain development. It is known that therapeutic positions, which are one of the individualized developmental care practices, are effective on sleep.This study was conducted to compare the effectiveness of three stair positioning pillows and positioning materials on the sleep-wakefulness status of preterm infants.
