Final answer:
To get her baby to feed, Jackie should stimulate the baby's rooting reflex, which causes the baby to turn its head towards anything that touches its cheek or mouth, aiding in breastfeeding.
Step-by-step explanation:
To encourage her baby to feed, Jackie should attempt to trigger the rooting reflex in her newborn baby. The rooting reflex is an instinctive behavior where a baby will turn its head towards anything that strokes its cheek or mouth. This reflex will cause the baby to turn its head in search of the nipple to begin feeding. On the other hand, the Moro reflex is associated with a baby's instinctive reaction to a sense of falling, the grasping reflex enables a baby to automatically grasp any object touching their palm, and the stepping reflex is characterized by a baby making stepping motions when held upright with their feet touching a flat surface. However, it is the rooting reflex that is directly linked to feeding.
