At birth, a baby's bones are still largely cartilage, but they progressively ossify and harden as the child grows. By adulthood, the bones have fully developed with the completion of growth plates, resulting in a stronger and denser bone structure. With age, bones can lose density and become more brittle, especially in the case of osteoporosis.
