The World Health Organization defines preterm birth as any birth that takes place before the 37. week of gestation (WHO, 2018). WHO estimates that there are 15 million prematurely born babies across the world, and the number is growing. Medical and technical advancements enable the survival of increasingly immature preterm babies, but their survival often has consequences in the form of many difficulties that present a challenge for the whole family. It is estimated that around 40% of prematurely born children have certain feeding and swallowing difficulties (Arvedson i sur., 2020). The aim of this paper is to determine if prematurely born infants are different than infants who are born on their due date regarding the presence of visible signs of feeding and swallowing issues and to determine whether the prematurely born infants of different gestational age differ in this signs. Also, the existence of a connection between the presence of signs of feeding and swallowing problems and the quality of life of the family will be determined in order to take the first step toward developing a system that offers support and counseling to the entire family while emphasizing the necessity of implementing speech-language therapy activities in NICU. Research participants are parents of prematurely born infants whose corrected age is under 7 months and parents of full-term infants whose age is under 7 months while the measuring instruments used to conduct this research are: NeoEAT – Breastfeeding (Pados i sur. 2017; Pados i sur. 2018a; Pados i sur, 2019a), Bottle-feeding (Pados i sur. 2017; Pados i sur. 2018b; Pados i sur, 2019b), Mixed Feeding (Pados i sur. 2017; Pados i sur. 2019c; Pados i sur, 2020) and Feeding Impact Scales (Estrem i sur., 2020). A significant difference was determined between preterm infants and full-term infants regarding the presence of visible signs of feeding and swallowing difficulties using. However, significant differences were not found when observing the presence of visible signs of feeding and swallowing difficulties in preterm babies that were compared considering their gestational age. A significant positive correlation was found between the presence of visible signs of feeding and swallowing difficulties and the influence of feeding on the quality of life of the parent and the entire family which shows the necessity of implementing family oriented therapy for feeding and swallowing difficulties beginning at the earliest possible age.
