Background and purpose:~Preterm infants need to receive intensive care in a neonatal intensive care unit (NICU) to survive, but the sleep of preterm infants is disturbed by the environment of the intensive care unit, invasive treatment and care activities. When a preterm infant's sleep is interrupted, it not only affects his physical growth, behavior and emotional development, but also affects his recovery from illness and the length of hospital stay, and even affects his sleep quality and development after returning home. However, medical personnel are busy with clinical practice, seldom pay attention to the sleep development of preterm infants. In the past, few studies paid attention to the factors that affect the sleep of preterm infants after returning home, and few studies also explored the sleep and physical and mental health of preterm infants and their main caregivers after returning home. Sleep intervention in preterm infants was mostly a single outcome indicator; besides, past studies lacked objective sleep instruments and long-term follow-up studies.~Based on the above research gaps, this research plan to construct an early sleep Facilitation program and to explore the effects of the Early Sleep Facilitation Program on the sleep and health of preterm infants and the sleep, stress, quality of life and attachment of the caregiver for a Long-term follow-up research.~The proposed study has six specific aims:~Explore the effect of Early Sleep Facilitation Program on the sleep of preterm infants during hospitalization and after returning home.~Explore the effect of Early Sleep Facilitation Program on the health of preterm infants during hospitalization and after returning home.~Explore the effect of Early Sleep Facilitation Program on the sleep of the caregiver after preterm infants during hospitalization and after returning home.~Explore the effect of the Early Sleep Facilitation Program on the stress of the caregivers of preterm infants during hospitalization and after returning home.~Explore the effect of Early Sleep Facilitation Program on the quality of life of the caregivers of preterm infants during hospitalization and after returning home.~Explore the effect of Early Sleep Facilitation Program on the attachment of the caregivers of preterm infants during hospitalization and after returning home.~Methods:~This randomized controlled trial will adopt a longitudinal repeated measures design to examine the  Early Sleep Facilitation Program  on the sleep and health of preterm infants and the sleep, stress, quality of life and attachment of the caregiver. Preterm infants and the caregiver were recruited by convenience sampling in Neonatal Intensive Care Unit and Infant Intermediate Care Unit of a medical center in northern Taiwan from July in 2020 to December in 2022. There are two different intervention modes (intervention group and control group), the intervention group receives  Early Sleep Facilitation Program  and the control group receives routine care. The program is divided into two stages. The first stage is to provide sleep circadian rhythm training for preterm infants during hospitalization, and the second stage is to give the caregiver the nursing guidance to promote preterm infants' sleep before preterm infants discharged from the hospital. Moreover, continue to give nursing guidance and follow its implementation status after the first month and the second month after discharge. The control group receives routine care and provide general discharge care and nursing guidance. The questionnaires and physiological measurements will be used to collect the data. The two groups will collect data during hospitalization, one week before discharge, and the first month and the second month after discharge. We will use generalized estimation equations method to analyze research data.
