The idea
Infant growth follows the patterns set before birth: cephalocaudal, head first and legs last; proximodistal, centre outward; and mass-to-specific, gross before fine.
In practice
A baby reaching with the whole arm months before grasping with the fingers.
Where people slip
The patterns predict order, not exact timing; every motor milestone in this unit follows them.
Your place on the trail
Every lesson rests on earlier ones and opens later ones. Tap any to jump.
