For children born in the three to five years preceding the survey, BRSFEDUR (M4) reports the calculated months of breastfeeding for those who are no longer being breastfed.
The related variable BRSFEDMO (M5) differs by including children who were still breastfeeding at the time of the interview. The variable BRSFEDCAT provides categorical information about breastfeeding, by indicating whether children were ever breastfed, and, if so, whether they are still breastfeeding.
The maximum period allowed for BRSFEDUR during the data editing (by survey administrators) was the interval between the date of birth of the child and the date of interview. See the "Comparability" tab for more information regarding comparability across phases.
