A. “The palmer grasp reflex should disappear by 3 months of age.” B. “The palmer grasp reflex helps my baby hold a bottle or a spoon.” C. “The palmer grasp reflex is stronger than the plantar grasp reflex.” D. “The palmer grasp reflex is present at birth and lasts until 6 months of age.”

Answer and Explanation

Choice A:

the palmer grasp reflex should disappear by 4 to 6 months of age, not 3 months.

Choice B:

the palmer grasp reflex does not help the infant to hold a bottle or a spoon.The infant does not have the coordination or strength to do so until around 9 months of age.

Choice C:

the palmer grasp reflex is not stronger than the plantar grasp reflex.Both reflexes are equally strong and disappear around the same time.

The normal range for the palmer grasp reflex is from birth to 4 to 6 months of age.

Choice D:

This reflex is elicited by placing an object in the infant’s palm and the infant will curl their fingers around it.

This reflex helps the infant to develop voluntary grasping skills later on.
