Until recently, and maybe until now, most of the studies on the preterm infants development and their parents focused mainly on the infant and their mothers. The current article, after a brief introduction about preterm newborns and how this impact on fathers, I point out the main results of this research that had focused only fathers. This results agree to emphasize that in a newborn situation that requires hospitalization in a Neonatal Intensive Care Unit (NICU), fathers play a fundamental role supporting their partner and the mother-child relationship, promoting a healthy neuropsychological development of the baby. Therefore, it is necessary to structure the support programs specifically aimed at fathers of premature babies.
