Main concern regarding this recommendation is, whether EBF supports rapidly growing infant with adequate nutrition. Methods: A cohort of randomly selected new-borns was followed up at two, four and six months, to study feeding pattern and physical growth. Feeding practices and socio-demographic data were collected using an interviewer administered questionnaire. Weight & length were measured using standard techniques. Results: EBF rates were very high in this cohort of children. One main reason to stop EBF was growth faltering. Only some children showed a catch up growth by stopping EBF. At two, four and six months, weight faltering rates among EBF babies were, 11.1%, 20.1% and 13.2% respectively. Length faltering had a similar pattern, but with a higher rate at all ages. Conclusions: EBF up to six months did not cause growth faltering in the majority. In the majority, no identifiable cause for growth faltering was found. Possible genetic influence on growth faltering was not considered when stopping EBF.展开更多
