In Australia, one of the most frequent reasons for not breastfeeding is a previously unsuccessful experience. This qualitative study used an appreciative inquiry approach to co-design a model of peer and professional breastfeeding support, in a metropolitan area of New South Wales (NSW) Australia, in collaboration with women who have had previous negative experiences of breastfeeding. In total, 30 mothers, health professionals and peer supporters participated in a two-part study, involving interviews and a collaborative workshop. The data were analysed using content analysis. The appreciative inquiry approach led to a solution focused attitude among participants and a commitment to improving breastfeeding support. We noted a level of apathy when the participant groups were interviewed individually prior to the collective workshop. During the collaborative workshop, all three participant groups came together to look at what was currently working well and designed improvements for the future. Midwifery care was identified as important for the start of the breastfeeding journey, during pregnancy and for the first 1-2weeks after birth, but thereafter it was community and trained peer counsellors who were prioritised for breastfeeding support. Participants identified the need for a variety of support options including face-to-face meetings, Skype meetings, phone calls and/or texting. Workshop participants emphasised the need for women, especially those with previous negative experiences, to be linked in with their local peer support community group. An appreciative inquiry approach brought together all key stakeholders to develop practice-based change which included the end user and care providers. The collaborative workshop enabled participants to come together, as individuals, rather than as designated health professionals or trained peer counsellors, or breastfeeding women with negative experiences. This led to a unified approach and a harnessing of collective energy to initiate positive change.
