The answer is innate involuntary behavior patterns. Innate involuntary behavioral patterns help the infant survive until they can learn more complex strategies. Some movements are natural, occurring as part of the baby's usual activity. Others are responses to certain actions. Reflexes help classify normal brain and nerve activity. Some reflexes occur only in specific phases of development. The five infant reflexes include: grasping reflex, startle (moro) reflex, rooting reflex, stepping reflex, and sucking reflex.
