Assessing characteristics of mother–infant dyadic synchrony among vulnerable mothers using the Infant CARE-Index

This study offers novel observational insights into early relational dynamics in mother-infant dyads affected by maternal mental health history-an area underexplored in Danish postnatal care. By applying the Infant CARE-Index, the findings highlight specific behavioural patterns that may hinder bonding and development. These results underscore the need for relationship-based, targeted, and flexible interventions to support vulnerable dyads and promote healthier developmental trajectories.
