Impact of Early Bonding During the Maternal Sensitive Period on Long-Term Effects: A Systematic Review.

This research project examines the long-term effects of maternal-neonatal bonding during a mother's "sensitive period." The review explores how early contact between a mother and her newborn can affect their psychosocial and emotional well-being in the future. Within an hour after birth, oxytocin levels increase for mothers, while catecholamine surges enhance neonates' memory retention to encourage immediate skin-to-skin contact (SSC), which promotes breastfeeding with benefits, such as quicker placenta expulsion, less bleeding, and lower stress. As per sources to date, there is no systematic review on this subject; however, numerous studies exist regarding short-term outcomes, exclusive breastfeeding, and childhood problems. The exploration involves rigorous searches of academic databases following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for transparency and reproducibility by using the Population, Intervention, Comparison, and Outcome (PICO) framework. Of the 516 initially identified articles, only five were relevant based on refined selection criteria, making it clear from the analysis that sensitive-period bonding produces long-term impacts in infants. Few studies are available, particularly in recent years; thus, more research is required in this area.
