False.
Hyaline Cartilage
yes
Yes, it is true that in a developing fetus, the long bones are initially formed from hyaline cartilage. This cartilage serves as a scaffold that is gradually converted into bone through a process known as endochondral ossification.
Hyaline cartilage
The long bones of a fetus are constructed mainly of cartilage during fetal development, which eventually ossifies and becomes bone as the fetus grows. This process is known as endochondral ossification. The primary long bones in a fetus include those found in the limbs, such as the femur, tibia, fibula, humerus, radius, and ulna.
Hyaline cartilage actually it is articular cartilage that lines the end of long bones. depending on the age of the body and whether it is a fetus or child/adult. hyaline cartilage disappears around the 6th week old fetal development and is replaces with osseous tussue. there is a region, farther from the marrow cavity, that consists of typical hyaline cartilage that shows no sign of transformation into bone in the early years of growth. it is in the "zone of reserve cartilage"
Bone starts as cartilage in the fetus. As the fetus takes on the final shape, this cartilage arranges, and enough hardening occurs in the limbs to allow the creature to stand shortly after birth. At that point, all the bones begin to harden, and continues to harden all throughout life. Bones contain a level of cartilage all the way until old age.

Babies are not mostly cartilage, fetuses are. The reason why they are is because they undergo a process known as endochondral ossification. Basically, the fetus creates an outline of what the skeleton should look like with a hyaline cartilage model. Then this cartilage is replaced with the bone cells which create a bone matrix.
At the time of birth a child has 300 bones but these bones fuse with each other as the child grows up and at adulthood the figure drops to 206.
