We assessed whether the negative association between maternal postpartum depression (PPD) and infants' development of joint attention (gaze following) generalizes from WEIRD (Western, Educated, Industrialized, Rich, and Democratic) to Majority World contexts. The study was conducted in Bhutan (N = 105, M = 278 days, 52% males) but also draws from publicly available Swedish data (N = 113, M = 302 days, 49% males). We demonstrate that Bhutanese and Swedish infants' development follows the same trajectory. However, Bhutanese infants' gaze following were not related to maternal PPD, which the Swedish infants' were. The results support the notion that there are protecting factors built into the interdependent family model. Despite all the benefits of being raised in a modern welfare state, it seems like Swedish infants, to an extent, are more vulnerable to maternal mental health than Bhutanese infants.
