# Get Your Free Resource Here—Timeline of Reflex Development Chart

[Primitive and postural reflexes](https://moveplaythrive.com/index.php?Itemid=913 "Get info about each primitive and postural reflex") are involuntary, stereotypical movements that all healthy infants do in early life as part of development. These innate movements build the brain, body, and sensory systems—setting the foundations for physical, emotional, and cognitive skills. Each primitive and postural reflex has vital functions and an approximate ideal lifespan.

Get this ***Timeline of Reflex Development Chart*** for a useful guide showing the optimal windows for when primitive and postural reflexes ideally emerge, develop, and integrate. Note: An integrated primitive reflex is one that is dormant and no longer activated by its specific sensory input. Postural reflexes are "lifelong" and ideally emerge, develop, and continue serving us for life. We work with both primitive and postural reflexes in the [Brain and Sensory Foundations program](https://moveplaythrive.com/index.php?Itemid=362 "Brain and Sensory Foundations, First Level, CEU course").
