How many bones does a newborn baby have?

A newborn baby has approximately 300 bones at birth. This count is higher than the 206 bones that an adult typically has. The reason for this difference is that many of a baby's bones are not fully developed and consist of cartilage, which is softer and more flexible than bone. As the child grows, some of these bones fuse together, resulting in the standard adult count of 206 bones. Therefore, 300 is the correct answer as it accurately reflects the number of bones a newborn possesses before the fusion process begins.
