Continuous Delivery Room Skin-to-skin-study for Moderate and Late Preterm Infants

The goal of this randomized controlled trial is to compare the effect of direct skin-to-skin contact in moderate and late preterm infants. The main questions it aims to answer are: * does skin-to-skin contact in moderate and late preterm infants influence gene expression in the stress signaling pathway? * does skin-to-skin contact in moderate and late preterm infants improve the short- and long-term outcome? Participants will either get immediate separation after vaginal birth or receive immediate skin-to-skin contact. Researchers will compare these two groups to answer the proposed questions.
