Cue Based Feeding

The goal of this feasibility study is to assess the feasibility to implement a feeding strategy for preterm infants. The main questions it aims to answer are: * Is it feasible to implement the PoP-intervention in a level 3a category Neonatal intensive care unit? * Is the PoP-intervention acceptable for parents of preterm infants and health care personnel working in Neonatal intensive care unit? Parents of preterm infants and health care personnel will be asked to follow a protocol of a feeding strategy based on the preterm infants development and cues throughout the NICU-stay.
