Brief summary

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).

Interventions

BEHAVIORALBaby-Led Introduction to SolidS (BLISS)

Caregivers were instructed to offer age-appropriate solid foods that infants could grasp and self-feed, following BLISS principles, with emphasis on safe textures, iron-rich foods, and close supervision during feeding.

BEHAVIORALParent-Led Weaning (PLW)

Caregivers fed infants complementary foods using spoon-feeding techniques, progressing food texture and consistency according to age-appropriate feeding recommendations.
