In Luzhou, China, where grandmothers often serve as primary caregivers for infants, the past and the future haunt new mothers suffering from postpartum depression. In this article, I draw upon longitudinal interviews conducted with 10 families in Luzhou as part of a larger multisited ethnography of postpartum depression and anxiety. I argue that the grandmother-mother-baby triad model of infant care in interior urban China accentuates the pain of depressed postpartum mothers by making it difficult for them to rid their homes of the ghosts of past traumas and lost futures. Mothers resent and fear grandmothers even as they rely on them to care for their babies. Memories of trauma, perceived displacement by the grandmother as the mother figure for their babies, and lack of control over their households and children characterize depressed postpartum mothers' experiences. Mothers primarily blame their mothers-in-law for their unhappiness even as they depend on themselves to "self-adjust." [postpartum depression, grandmothers, motherhood, China]
