How many bones are there in a newly born infant?

Newborn babies have approximately 300 bones at birth, which is about 94 more than adults. As children grow, many of these bones fuse together through a process called ossification. For example, the skull bones fuse to form the cranium, and sacral vertebrae fuse to form the sacrum. Adults end up with 206 bones. 206 is the adult count, not newborn.
