Conclusions. Examining four different domains of child development, we found a prospective impact of postpartum PTSD symptoms on children’s social–emotional development at 2 years of age. Our findings suggest that both boys and children with an early difficult temperament may be particularly susceptible to the adverse impact of postpartum PTSD symptoms. Additional studies are needed to further investigate the mechanisms at work.
