Sadness in mothers' 'baby-talk' predicts affective disorder in adolescent offspring.
'Baby-talk' is common across cultures. It underpins infant vocal preferences, and helps regulate infant engagement. Its longer-term significance is unclear. In a longitudinal study, we found indications of 'sadness' in postnatally depressed mothers' baby-talk statistically mediated effects of maternal depression on offspring adolescent affective disorder.
