A cross sectional study survey was carried out among physicians who work at children's clinics in Pelotas. The doctors were interviewed by medical students about the prescription of tea for children under six months, risk factors and breastfeeding. About half of the interviewed physicians prescribed tea. The main reasons for that were: intestinal colic (35%), diet suplementation (21%), and oral rehydration (18%). The relationship between tea and diarrhoea, tea and malnutrition, tea and weanning was acknowledged by 19%, 47% and 83% of them, respectively. These association remained significant (p<0.05) even after adjustments were allowed for graduation time and pos-graduation courses. The conclusion is that some commom aspects of children's diet are not well managed by most of these doctors.
