Adults have 206 bones in their bodies, but the same is not true for infants. The skeleton of a newborn baby has approximately 300 different components, which are a mixture of bones and cartilage. The cartilage eventually solidifies into bone in a process called ossification — for example, the kneecaps of newborns start off as cartilage and become bone in a few years. Over time, the "extra" bones in infants fuse to form larger bones, reducing the overall number of bones to 206 by adulthood.
