Baby-Led Introduction to SolidS (BLISS) study: A randomised controlled trial of a baby-led approach to complementary feeding

In 2002, the World Health Organization recommended that the age for starting complementary feeding should be changed from 4 to 6 months of age to 6 months. Although this change in age has generated substantial debate, surprisingly little attention has been paid to whether advice on how to introduce complementary foods should also be changed.
