Exclusive breast feeding versus supplementation: a prospective study in a rural south Indian community

In a non-interventional, prospective study in three south Indian villages, exclusively breast-fed infants were compared with those given supplements in addition to breast milk. The supplements provided less than 30% of caloric requirement in most cases. Both groups grew similarly and the growth curves showed a sharp fall after the third month. Whether this fall is physiological, or a result of poor socio-economic conditions is not clear.
