This article argues the importance of ensuring initiatives aimed at improving children's social and emotional well-being are based on sound participatory principles. The discussion posits links between the recognition of children, dialogic approaches to participation, changing conceptualisations of children and childhood, and children's well-being. It explores these links in light of one particular initiative, Seasons for Growth (Graham, 1996, 2002, "Seasons for Growth; Loss and Grief Education Program. MacKillop Foundation"), an education programme built around emerging evidence that giving children a voice assists them to adapt to family change. The paper concludes with insights into what is involved when we locate notions of "having a say" as a key element in promoting children's well-being.
