BLISS: Baby-led introduction to solids

Researcher profiles:

Can infants self-regulate eating?

Current recommendations suggest that infants are introduced to complementary foods around 6 months of age using purees that are traditionally spoon-fed to the infant. Over time, the child then progresses to mashed and lumpy foods with the expectation that by the time the baby is 12 months of age, they are eating mostly family foods.

Whole foods from the start

An alternative, baby-led approach bypasses purees and introduces whole foods right from the start of complementary feeding, which the baby feeds themselves. Proposed advantages of a baby-led approach include improved energy self-regulation as the infant is more in control of what and how much they eat, greater family interaction as the baby joins in family meals, and convenience. However, concerns have also been raised regarding choking and the potential for an inadequate iron intake.

100 families will help

Very little research exists internationally, despite baby-led weaning being a popular approach anecdotally.

Our randomised controlled trial uses a modified form of baby-led weaning, called Baby-Led Introduction to SolidS (BLISS). We will follow 100 families that receive guidance and support to follow a baby-led approach to the introduction of solids and 100 families that introduce solids in the usual manner.

We want to know what these children eat, how their families function, whether growth differs between the two groups, and what happens in terms of iron status and choking during the first two years of life.
