  It would seem, then, that sometime between 3 and 9 months, babies are arguably already on their way to a concept of desert.  Much remains to be discovered about the contours of their concept and its subsequent development.  As Hamlin points out, apart from the helper-hinderer contrast, we don’t know how they determine who deserves what.  Relevant here is the finding that babies prefer not only helpers, but also those who are relevantly similar, who like the same toy or candy, for example (Mahajan and Wynn 2012).  How much of their apportionment of desert is dependent on such factors as opposed to factors that adults might consider morally relevant, like fairness, responding to need, and so on. How, if at all, does their early concept connect to egalitarian notion of fairness?
