Answer 1

The Moro reflex is an instinctive behavior present in infants from birth until about three or four months of age. It occurs in response to a sudden loss of support and involves spreading out the arms, bringing them back in, and usually crying.

Step-by-step explanation:

The Moro reflex is an instinctive behavior that is normally present in an infant from birth up until about three or four months of age. It occurs in response to a sudden loss of support when the infant feels as though it is falling. It involves three distinct components: suddenly spreading out the arms, bringing the arms back in toward the body, and, usually, crying. If the baby really were falling, these motions might help it reach out and grab its mother or another caregiver.
