This study was conducted to investigate the weaning practice of 198 infants in Taejon city in October, 1998. Information on infant feeding and weaning practices were obtained by interviewing mothers in gynecologist and pediatric clinics located in Taejon. The results obtained were as follows : In the survey 37.4% of the infants were breast-feeding, while 31.3% of them were bottle-feeding and 29.3% of them were mixed-feeding. The reason for bottled-feeding was due either to the lack of breast-milk secretion or motner’s job. The educational level of the mother and maternal job affected the feeding methods before weaning. Lower rates of breast-feeding were found among mothers witn a lover level of education. The breast-feeding rate was lower in full-time and part-time job worker groups than in housewife. There was no significant difference in the feeding methods according to family income. Among the subjects, 71.5% of infants began to be weaned within 7 months. The onset of weaning was delayed in the full-time worker group. There was no significant difference in the onset time of weaning according to feeding method, the educational level of the mother, and family income. 60.6% of infants received fruit juice and 29.6% of them received cereals for first-given-supplementary food. ‘For baby’s nutritional status’ was the most common motivation for the onset of weaning. Commercially prepared foods were used more than home-made food for supplementary food.
