The trial will be conducted in a total of 50 community clusters (Mahallas - smallest geographic units in Dhaka -see details below in Sampling Scheme), with 25 clusters in each study group. The peer counseling education intervention will be delivered to the mothers, by locally recruited and trained peer counsellors, starting in the third trimester of pregnancy until the child is one year of age. The peer counseling education will be offered to eligible pregnant women identified by household surveys over 3 months in each community cluster in the intervention group. Using a similar approach to recruitment, a cohort of mother-infant dyads, who will receive standard maternal and child health care programs, will be identified in the control clusters.
