Solid foods and infant growth

Primary Objective

HELP US GIVE BABIES A SOLID START ON SOLIDS! We are interested in learning how consuming different types of solid foods during early complementary feeding affects growth, neurodevelopment, sleep, and the bacteria in the gut. The findings from this study may help to inform future dietary guidelines for infants.
