It's not entirely correct to say a baby is born with more bones than they will have as an adult, because what has happened is that the bones are simply not fused or developed completely. The bones which form the face and skull are slightly separated at birth, to allow for the birth process without damaging the brain inside, and those spaces will grow together and fuse as the child grows. The feet and lower legs are primarily bits of bone with lots of cartilage connecting it all, again this allows the baby to fit in the womb and be born without major damage. Since the baby won't need to walk and bear its own weight, those structures graduallly calicify over the next year or so, and eventually take on the appearance you would recognize as bone. At the ends of all the bones are growth plates, where the bone tissue actually grows to extend length, and these will disappear when puberty and growth are finished. The bones which make up the rib cage, spine and pelvis are all present at birth, and there are no extras there. The lower spinal vertebrae fuse together during childhood and early adulthood, usually the last 2 or 3 vertebrae, you would refer to that part as your tail bone. The bones are still present even in an adult, just fused together, much like the bones of the skull. So a baby isn't really born with more bones, just the bones in separate parts which will fuse during growth, and eventually leave them with the full adult compliment of 206.

When you were a baby, you had tiny hands, tiny feet, and tiny everything! Slowly, as you grew older, everything became a bit bigger, including your bones.

A baby's body has about 300 bones at birth. These eventually fuse (grow together) to form the 206 bones that adults have. Some of a baby's bones are made entirely of a special material called cartilage. Other bones in a baby are partly made of cartilage. This cartilage is soft and flexible. During childhood, as you are growing, the cartilage grows and is slowly replaced by bone, with help from calcium.

By the time you are about 25, this process will be complete. After this happens, there can be no more growth — the bones are as big as they will ever be. All of these bones make up a skeleton that is both very strong and very light.
