To “make kin, not babies” is what Donna Haraway has recently proposed in response to the so-called “Anthropocene”. Building on other critical engagements with Haraway’s proposal, this paper interrogates it from a childist perspective. While striving towards a “pro-child” position on kinship, Haraway only goes so far in explicating this aim. The paper suggests that challenging adultism as well as attention to children's ongoing kinship practices are required.
