The Effect of Lullaby and Breastmilk Smell on Preterm Newborns

The goal of this clinical trial is to investigate the effect of live lullaby from mother voice, and breast milk smell on pyhsiological parameters, comfort and maternal attachment levels of preterm newborns who are between 35-37 weeks of gestation at the time of the study and the level of pospartum depression of mothers. The main hypothesis are: H0: The live lullaby from mother voice and breast milk smell have no effects on pyhsiological parameters, comfort and maternal attachment levels of preterm newborns H1: The live lullaby from mother voice has effects on pyhsiological parameters, comfort and maternal attachment levels of preterm newborns H2: The breast milk smell has effects on pyhsiological parameters, comfort and maternal attachment levels of preterm newborns H3: There is differences between the live lullaby from mother voice and the breast milk smell interventions in terms of preterm newborns' physiological parameters, comfort and maternal attachment levels. H4: The postpartum depression level of mothers in experimental groups (lullaby group and breast milk group) is lower than the control group. Participants will be in three groups according to the interventions. The preterm newborns who are going to listen a live lullaby from their mothers' voice will be the first group (Lullaby group). The preterms in the second group (Breast milk group) are going to smell their mothers' breast milk. The preterms in the third group (Control group) are going to recieve rutin nursing care interventions.
