* More cartilage: A newborn's skeleton has more cartilage than an adult's, which makes it more flexible. This cartilage will gradually turn into bone through a process called ossification.
* Softer bone: Newborn bones are also softer and more porous than adult bones. This makes them more vulnerable to fractures, but also allows them to grow and change shape more easily.
* Fontanels: A newborn's skull has soft spots called fontanels, where the bones haven't yet fused together. These fontanels allow the skull to compress during birth and also help the brain to grow.
So, while a newborn's skeleton is made of bone, it's very different from an adult's skeleton in terms of its flexibility, density, and overall composition.
