An infant's skeleton is actually mostly cartilage. If a fetus's skeleton was bone, childbirth would be much harder. As calcium deposits in that cartilage, it begins to convert to bone.
hyoid bone
As a baby, most of your skeleton was primarily composed of cartilage, which is a flexible and softer tissue. Over time, this cartilage gradually ossifies and transforms into bone through a process called endochondral ossification. By adulthood, most of the skeleton becomes a rigid structure made mostly of bone, which provides support and protection for the body.
