How many bones does a newborn human baby have versus an adult?
A human baby is born with 176 true bones, but its skull is actually three bones that have not yet fused. (This is a nice feature since it allows for easier delivery when the baby is born.) As a baby grows, the three bones fuse into one. Some of a baby’s other bones are called cartilaginous bones, which means they have not yet calcified. By the time a baby reaches adulthood, bones will total 206 in his or her body.
