RESUMEN
The aim of the present study was to assess ability of pregnant women (n=82) to acquire guidance on breastfeeding, babys sucking habits, and oral hygiene. Subjects were interviewed before and after their enrolment in the pregnancy orientation program at Piracicaba Dental School, University of Campinas (UNICAMP). Results showed that all subjects improved their knowledge on all behavior aspects as well as their ability to follow guidance offered in this study. Information provided during the pre-natal period seems to help reduce incidence of early introduction of foods and weaning. To guarantee the success of programs designed to assist pregnant women, it is wise to use a systematic follow-up to motivate mothers after childbirth to keep up with guidance given in such programs, concerning not only information, but also emotional and instrumental support.
