Final answer:
The Moro reflex typically disappears around 3 months of age in newborns and infants.
Step-by-step explanation:
The Moro reflex typically disappears around 3 months of age. The Moro reflex is an instinctive behavior present in newborns and infants that occurs in response to a sudden loss of support. It involves spreading out the arms, bringing them back in toward the body, and usually crying. This reflex helps the infant reach out and grab onto a caregiver if they were actually falling.
