OBJECTIVE: This study identified strategies for promoting breastfeeding involving pregnant women, breastfeeding women and actors of the social support network for the breastfeeding process. METHODS: This qualitative study was guided by action research and the focal group technique to collect data. Focal Group 1 consisted of four pregnant and six breastfeeding women; Focal Group 2 consisted of six family members; and Focal Group 3 consisted of thirteen health professionals. The focal groups were guided by the following questions: What breastfeeding promotion and support actions should be done? How should they be performed? Who should perform them? The conversation sunder went thematic content analysis and were interpreted in the light of Paulo Freire's theoretical constructs: dialogue, ethics and problematization. RESULTS: Four themes were emerged from the conversations: dialogue-based educational actions involving the social support network during the vital cycle; educational actions in schools; educational actions in the media; ongoing counseling at Family Health Units. CONCLUSION: The constructed strategies were centered on dialogue and active listening. Both should be present during the entire vital cycle and in the Family Health Strategy, and involve all actors of the social support network. These strategies may disrupt the unidirectional transmission of the educational practices that promote breastfeeding.
