Limitations
This study has some limitations. First, there might be a reporting bias because the infants’ neuropsychological development outcomes were reported by their mothers. Women in the intervention group may have become more emotionally literate and thus more likely to notice specific reactions in their infants.

Thus, our results on infant outcomes are exploratory and should be interpreted with caution. Second, most participants reported a high socioeconomic status, limiting the generalizability of the findings to disadvantaged pregnant populations. Third, some confounding factors were not measured in our study, which may have affected the results of the mediation analysis. According to a concept map [
