developmental progression

The development of normal spinal curvature represents a crucial aspect of human growth and posture establishment. This progression, occurring from early childhood through adolescence, demonstrates the remarkable adaptability of the vertebral column in response to developmental milestones and gravitational demands. The illustration showcases four key stages of spinal curve development, highlighting the transition from infancy to mature posture, with particular emphasis on the formation of primary and secondary curves.

Rolling over marks an exciting milestone in your baby's development, representing their first major independent movement. This crucial skill typically emerges between 4 and 6 months of age, though some babies may achieve it earlier or later. Understanding this developmental milestone helps parents support and encourage their baby's growing mobility while ensuring safety during this new phase of movement.
