The Infant Feeding Practices Study II (IFPS II), conducted by the Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) in 2005–2007, is a longitudinal study that followed about 2,000 mother-infant pairs from the third trimester of pregnancy throughout the first year of life to study a variety of infant feeding practices.

In 2012, the FDA and CDC conducted the Year Six Follow-Up (Y6FU) study among mothers and children who participated in the IFPS II to characterize the health, development and dietary patterns of these children at 6 years of age.
