Abbreviations: CI = confidence interval; FBF = full breastfeeding. a Adjusted for maternal education, race/ethnicity, household income, age, parity, delivery mode, prepregnancy weight, gestational weight gain, frequency of feeds at 1, 3 and 6 months (time-varying), physical activity level at 3 months postpartum, and infant birthweight and sex. b Reference category = FBF 1 month. c Reference category = time 1 month.
