“…Online maternal mentalization during infancy has been positively associated with children's language acquisition in toddlerhood (Laranjo & Bernier, ), executive functioning (Bernier, Carlson, Deschênes, & Matte‐Gagné, ), school readiness in preschool (Bernier et al., ), and theory of mind development (e.g., Devine & Hughes, ; Kirk et al., ; Meins et al., ). Furthermore, high prenatal (offline) as well as postnatal (online) maternal mentalization predicts lower levels of internalizing and externalizing behaviors in toddlerhood (Meins, Centifanti, Fernyhough, & Fishburn, ; Smaling, Huijbregts, van der Heijden, van Goozen, & Swaab, ), suggesting that maternal mentalization can buffer against the development of conduct problems (e.g., Hughes, Aldercotte, & Foley, ). Thus, understanding the processes by which online maternal mentalization relates to other positive aspects of mother–infant and mother–father–infant interactions, namely maternal sensitivity and family triadic interaction (e.g., Feldman & Masalha, ; McHale & Rasmussen, ), can help illuminate important precursor of early development.…”
