Quizplus · Accepted Answer

Dev is likely in stage two of Piaget's sensorimotor development, which is the primary circular reactions phase (1-4 months). During this stage, infants start to repeat actions that are pleasurable or bring about a desirable outcome, like thumb sucking for comfort. Dev's preference for thumb sucking over a pacifier suggests he's engaging in behaviors that are self-soothing, a characteristic of this stage.
