Preterm infants' growth and developmental outcomes vary with illness severity and degree of neurological insult and unpredictable variations in outcomes exist even among healthy preterm infants. The variations in preterm infants' outcomes have led to the supposition that the neonatal intensive care unit (NICU) environment may negatively impact the health and development of these infants and significant research has been devoted to examination of light, noise, and caregiving interventions. Consequently, many NICUs have implemented neuroprotective strategies to reduce over simulation, promote sleep and facilitate brain development in high-risk infants including the grouping of care activities around a single caregiving event described as "clustering" or "bundling care". Yet, the number and type of caregiving activities that are included in bundled care and the timeframe between bundled care events has not been systematically studied. The inclusion and exclusion of certain care activities in any individual care event is often dictated by the infant's treatment plan or needs, but some activities like diapering may be optional. Understanding the impact of when to include optional, yet stress provoking interventions, will allow us to minimize overall environmental stress in hospitalized very low birthweight (VLBW) infants. Therefore, given the lack of data around bundled care, the investigators aim to explore through a randomized controlled design the impact of bundling diaper care activities on overall health of VLBW preterm infants. The investigators will include a focus on skin health because it is important to understand the benefits of decreased infant stress and any potential skin health trade-offs associated with longer versus shorter time between diapering care. Findings from this study will allow us to better understand the relationship between neonatal skin health while providing developmentally appropriate bundled care.
