Abstract: To evaluate the associations between parental/family early relational contact in the neonatal intensive care unit (NICU) and the post-discharge childcare quality and behavioural development up to 18-24 months of corrected age (CA). In a longitudinal cohort study (2017-2022), 215 preterm infants were followed. Early relational NICU contact (minutes/day) was measured daily using a 12-item observational checklist. Post-discharge childcare quality was assessed at 18-24 months with the Index of Child Care Environment (ICCE). Behavioural development was assessed using the Bayley Scales of Infant Development III and the Brief Infant-Toddler Social and Emotional Assessment. Multiple regression models examined the associations between these key variables, adjusting for clinical and demographic confounders. The cohort was predominantly male (57.67%), non-Hispanic (74.88%) and White (67.44%), with an average gestational age of 28.3 weeks. At 18-24-month CA, greater early skin-to-skin/soothing contact was linked to better language development (β = 0.33, p = 0.032), and integrated nurturing contact (characterised by holding combined with verbal interaction) was associated with better language and motor development in female infants (p's < 0.05); strong social support for caregivers was associated with infants' improved cognitive (β = 0.364, p = 0.018), language (β = 0.383, p = 0.008) and motor (β = 0.382, p = 0.015) outcomes. Infants with typical social-emotional competence received higher levels of human stimulation from their caregivers compared with those showing possible competence issues (OR = 1.439, p = 0.020). Greater early NICU contact and higher post-discharge childcare quality are associated with improved developmental outcomes in preterm infants at 18-24 months CA, showing the growing importance of environmental factors in infants' development. Future studies should explore targeted interventions that enhance early bonding and empower parents to support sustained developmental progress.
