Introduction: Adaptation to extrauterine life is harder for preterm newborn, because their sensitive stress treshold causes more stressful response to different stimuli. Individualized developmental care is based on understanding neborn's behavior and environmental adjustment to achieve conditions, important for development of susceptible newborn. Minimalizing stressful factors like light, noise, pain and creating positive sensory environment by initiating skin-to-skin contact, breastfeeding, nesting, hammock positioning, therapeutic massage and early vocalization are important elements of creating healing environment, where newborn is recognized as acitve participant in process of care. Purpose: To present importance of Individualized developmental care, different elements and nurse's role in Individualized developmental care. Methods: A descriptive research approach was used to review the literature written in Slovene and English. Literature was reviewed and analyzed. Literature was searched by CINAHL, Pubmed, Medline databases and Google Schoolar from October 2020 to April 2021. Discussion and conclusion: Many studies show impact of Individualized developmental care on behavior development. Organization of behavior consist of five subsystems, wich differentiate by constant interaction with environment. Every element of Individualized developmental care impact some of this five subsystemes. Nurse's role is to create optimal environmet and organize process of care. Skin-to-skin contact and breastfeednig impact stabilization of autonomic, motoric and self-regulatory subsystems. Nesting, hammock positioning and therapeutic massage support development of healthy sleep rhythm, state systems and strees regulation. Lower stress response to pain can also be achieved by swadling newborn during painful procedures. Elements that have impact on every behavior subsysteme are reducing light and sound intensity. Perceptions and work of medical staff are considered as the biggest limitations that impact the success of implementing Individualized developmental care. Parents recognize opportunity for improvement in nurse's relations and communication with family. They also want to get more comprehensible informations and be more active participations in process of care of their newborn. Implementation of changes can be accomplished by constant education, wich change nurse's perceptions and enable improvement of care.
