This randomized controlled trial aimed to compare adherence to two complementary feeding methods-Baby-Led Introduction to SolidS (BLISS) and Parent-Led Weaning (PLW)-in infants aged 6-12 months. A total of 130 infants aged 6-9 months were randomized to BLISS (n=65) or PLW (n=65) groups. Adherence was defined as self-feeding for BLISS and spoon-fed consistency for PLW. Follow-up continued until 12 months of age. The study found significantly higher adherence in the BLISS group compared to the PLW group (78.5% vs 52.3%, p=0.002).
