If you’ve ever been told your child “should be able to calm themselves by now”, this matters.
Decades of developmental research show that emotional regulation is not something children learn alone. It is built, slowly and repeatedly, through co-regulation with a safe adult. Before the brain can self-soothe, it needs to experience being soothed. This isn’t permissive parenting — it’s how nervous systems develop.
Studies on parent–child synchrony, the Still-Face paradigm, and social biofeedback consistently show the same thing: regulation is social before it becomes internal. Children borrow calm, learn meaning, and gradually build the capacity to regulate themselves through relationship. Co-regulation isn’t a parenting trend — it’s the cornerstone of emotional development.
