This paper examines comparable national surveys of breastfeeding from the Philippines carried out in 1973 and 1983. The probability of breastfeeding at selected infant ages is estimated, using the weighted life table. The conclusions are that a 5 per cent decline in the proportion of infants ever breast-fed occurred during the referenced period, and that median length of breastfeeding remained essentially the same.
