Detailed explanation-1: -When the child is somewhere between 2 and 6 years old, their cartilage patella starts forming a center of bone. Often, the kneecap will start to form bone at multiple centers within the cartilage. About 5 percent of the time, some of these bone centers do not fuse together with the main bone center.
Detailed explanation-2: -Babies have more bones than adults because as they grow up, some of the bones fuse together to form one bone. This is because babies have more cartilage than bone.
Detailed explanation-3: -Answer. During the ages 13 to 18, bones are still fusing together. Assuming you count the fusing as complete, 206 bones.
Detailed explanation-4: -It is the same number of bones as an adult but they are still growing and maturing. Human babies are born with close to 300 bones, most of them made of softer cartilage. As children age, some of those bones fuse together and harden into a finished skeleton of 206 bones.
