Final answer:
Newborns actually have more bones than an adult due to the presence of additional cartilage that will eventually fuse together to form larger, stronger bones.
Step-by-step explanation:
The doctor should MOST accurately respond that newborns actually have more bones than an adult. At birth, a baby's skeleton is made up of about 300 bones, which is more than the approximate 206 bones found in an adult. These additional bones in a newborn's body are actually due to the presence of more cartilage that will eventually fuse together to form the larger, stronger bones that adults have.
