Title: Mother-infant Signalling During Lactation Following Late Preterm and Early Term Delivery: An Investigation of Physiological, Psychological and Anthropological Factors
Brief Summary: This research will investigate different aspects of the 'signalling' between mother and infant during breastfeeding in a stressful situation following late preterm and early term delivery, when breastfeeding is often challenging. The researcher will conduct a single-blinded randomised controlled trial in Chinese mothers who deliver a late preterm infant (LPI; 34 0/7-36 6/7 weeks of gestation) and mothers who deliver a early term infant (ETI; 37 0/7-37 6/7) and plan to exclusively breast-feed.This study will investigate the role of the milk and infant gut microbiome as a potential 'signal' in this process. A relaxation intervention (meditation tape) will be used to reduce stress levels in mothers who are expressing breast-milk or breastfeeding their infant (born at 34 0/7-37 6/7 weeks completed gestation). This study will investigate whether lower levels of stress in the mother result in more successful and effective breastfeeding, leading to improved infant outcomes (better growth, longer sleep duration and reduced crying).
