👶 Primitive Reflexes: The Automatic Movements Every Newborn Is Born With

This simulator lets you trigger each primitive reflex on a virtual newborn and watch how the response changes as the infant ages, showing exactly when normal reflexes should fade.

🔬 What It Demonstrates

This simulator lets you trigger each primitive reflex on a virtual newborn and watch how the response changes as the infant ages, showing exactly when normal reflexes should fade.

🎮 How to Use

Select a reflex, apply its trigger stimulus, and slide the age control forward to see how the response strength changes from birth through around 6 months.

💡 Did You Know?

The Babinski reflex is unique among primitive reflexes because doctors also test for it throughout adulthood, since its reappearance later in life can signal a neurological problem rather than being expected and normal.
