Final answer:
Nesting toys are suitable for infants using a palmar grasp because they align with the developmental stage of using the whole hand to grip objects and also aid in developing motor skills and understanding object permanence.
Step-by-step explanation:
Nesting toys are indeed good for infants who use a palmar grasp. The palmar grasp is one of the first motor skills developed by infants, and it involves gripping objects with the whole hand, which is an outgrowth of the grasping reflex present at birth. Nesting toys complement this developmental stage by providing babies with appropriately sized objects that they can hold and manipulate, which is not only entertaining but also beneficial for their motor development and hand-eye coordination. Furthermore, as children grow, they will begin to understand object permanence and enjoy games like hide and seek, knowing that objects continue to exist even when they are not visible. These toys can assist in developing this cognitive skill by allowing the child to explore the spatial relationships as they learn to place smaller objects inside larger ones.
