Relative effects of breastfeeding intention and practice on maternal responsiveness

open access: yesInfant Mental Health Journal: Infancy and Early Childhood, Volume 41, Issue 1, Page 82-93, January/February 2020., 2020
ABSTRACT Our objective was to examine the differential effects of antenatal breastfeeding intention (BI) and breastfeeding practice (BP) on maternal postnatal responsiveness. We conducted a secondary analysis of longitudinal data from a subsample of 962 mother–infant dyads from a U.K.‐based birth cohort study the Avon Longitudinal Study of Parents and ...
