When Marc was an infant, he did not adapt well to change, but as a preadolescent, he will eventually accept changes if they are introduced gradually. Marc is most likely __________.

A slow-to-warm-up child may react cautiously or struggle at first when faced with change, but can adjust when given time and gradual introductions. Marc’s difficulty adapting as an infant and eventual acceptance of gradual change fit the slow-to-warm-up temperament. “Difficult” describes a more consistently intense, irregular pattern of reactions, while secure attachment is a bond with a caregiver, not a temperament type.
