Why does a child have more bones than an adult?

At birth, a baby has about 300-350 bones. The skeleton of a 25-year-old man already consists of 206 bones and does not change until the end of his life. A child has more bones than adults because some of the bones of newborns resemble cartilage in structure, as they grow older, these cartilages begin to ossify and grow together. This also applies to the skull of babies and the skeleton of the whole body. In the first two years of life, the bones of the skull grow and become overgrown with connective tissue.
