Question: Are babies born with more bones?

When you’re born, you have about 300 bones. By the time you’re a grownup, you’ve only got 206. The reason: As babies grow, some of their bones fuse together. Some infant bones are made entirely of soft, flexible tissue called cartilage that’s slowly replaced by hard bone as the baby develops.
