Verified step by step guidance

Understand the concept of infant reflexes, which are involuntary movements or actions that are typically observed in newborns and are crucial for survival and development.

Identify the Moro reflex: This reflex is characterized by the infant extending their arms and legs, then bringing them back in, often accompanied by crying, when they feel a sudden loss of support or are startled.

Clarify the Babinski reflex: This reflex involves the fanning out of the toes when the sole of the foot is stroked. It is a normal reflex in infants but may indicate neurological issues if present in older children or adults.

Explain the Palmar grasp reflex: This reflex occurs when an object is placed in the infant's palm, causing them to grasp it tightly. It is a primitive reflex that helps in bonding and interaction.

Describe the Rooting reflex: This reflex is triggered when the infant's cheek is touched, prompting them to turn their head towards the stimulus and make sucking motions. It aids in breastfeeding by helping the infant find the nipple.
