Touch: A Review of the Infant-Caregiver Relationship in the Neonatal Field

Abstract

Touch is a domain of enormous importance with implications in development, from birth, and across the lifespan. This work aims to review touch implications within infant-caregiver interaction. A non-systematic review of the literature was performed to assess the relevance of touch in the neonatal period, on attachment, and in child development. The review was conducted on PubMed database, in May 2023 using the following keywords: “infant”, “child”, “baby”, “newborn”, “neonatal”, “touch”, “contact”, “tactile”, and “attachment”. In the neonatal period, close skin contact facilitates caregiver sensitivity and responsiveness, promotes parent-infant reciprocity, reduces psychological distress both in caregiver and infants, and regulates the infant’s physiological systems (circadian rhythm, autonomic regulation). Touch also plays a crucial role in attachment by contributing to synchrony and self-regulation abilities, since secure attachment promotes learning of emotional regulation, social skills, and behavioural organization. Early sensory experiences are critical to developmental dimensions such as cognitive, motor, and socio-emotional, and influence physical growth rate. Concluding, in neonatal care services, touch should be systematically addressed in routine appointments. Within the field of infant-caregiver interactions, there is an urgent need to create a reliable tool for tactile assessment, allowing clear interpretations and the development of target interventions.
