Deleuze and Guattari's thought on remainders of childhood has proven its worth for educational theory and philosophy. However, thus far the discussion has not paid much attention to their notion of infantilization, which reveals a new dimension of their understanding of childhood. In this article, I develop both their concept of becoming-child and their concept of infantilization. This allows for thinking the remainders of childhood as inherently risky and ambiguous. I argue that this new understanding does not only paint a more complete picture of Deleuze and Guattari's theory of childhood, but is also better equipped to evade two dangers already identified in the Deleuze and Guattari scholarship: the romanticization of childhood on the one hand and the risky proximity of becoming-child to the acceleration of consumerist capitalism on the other hand.
