Do you know that
actually baby have more bones than adult does? Babies have more bones
than adults because as they grow up, some of the bones fuse together
to form one bone. This is because babies have more cartilage than
bone. New born babies have around 305 bones. A baby's skeleton is
mostly made up of cartilage. As a person grows up, most of this
cartilage turns into bone in a process called ossification. By
adulthood, the skeleton has just 206 bones.
When you're born,
not all of your bones are fused together yet. Ever felt a soft spot
on a baby's head? That's there because those parts of the skull
haven't come together yet (the lines where the separate bones meet
are called "sutures"). This happens partly because it makes
the birthing process easier (that's why a lot of newborns have pointy
heads), and partly because it leaves room for your body to grow. If
your bones were fused, they (and you) couldn't grow anymore.
