Mother-infant pairs will be recruited between infant age of 0 to 3 months to participate in monthly nutrition educations sessions and to encourage the women to continue exclusive breast feeding across all three groups. At 6 months of age, infants in each of the three groups were enrolled into the intervention study (upon receipt of informed consent). Data collection involves baseline, midline and endline measurements in the infants at 6, 12 and 18 months of age. In addition, participating mother-infant pairs will be visited weekly for delivery of the supplements and for morbidity monitoring and monthly for the measurement of anthropometry. Anthropometric measurements include: length (Infant/Child Shorr Height Board; Weigh and Measure, LLC ), weight (Seca 874 digital scale ), mid-upper arm circumference (MUAC) (Child MUAC Tape; Weigh and Measure, LLC), subscapular and triceps skinfolds (Holtain skinfold caliper ),head and chest circumference.
