Answer:
the match between the caregiver's responses to a child and the child's temperament.
Step-by-step explanation:
The baby goes through various stages of development where he begins to develop his skills and abilities. Among these developmental stunts, babies begin to realize objects, to recognize people, to indicate when they are dissatisfied, among other things. An important point of the baby's development occurs when there is a correspondence between the caregiver's responses and the child's temperament, this moment of development is what developmental researchers call "goodness of fit".
