In early age we begin to learn to develop a sense of verticality

In early age we begin to learn to develop a sense of verticality, going through stages like turning, sitting, crawling, standing and walking. The final result should be well coordinated walking, and a balanced and vertical posture with smooth, fluid motions. A well-controlled vertical posture and well-coordinated movement should be stable and of very good quality by the age of six to seven at the latest, when exams and tests at school often begin.
