As an infant and child's body develops and grows its bones slowly conjoin together so to become sturdier as it learns more rigorous movements and exercises. This is over the course of a childhood, obviously, and not just a few years. In fact your bones still grow together a tiny bit each year until you're an adult, and maybe slightly further afterwards, too.
Two characteristics of the fetal skeleton skull that differ from the adult skeleton are the presence of fontanelles (soft spots) in the fetal skull that allow for flexibility during childbirth, and the incomplete fusion of cranial bones in the fetus compared to the fully fused bones in adults.
The fetal skeleton is much softer, it has far more bones which fuse by adulthood. also the proporions are much more different, the skull of a fetus is much big in comparison to its body. obviously the fetal skeleton is much much smaller and is more fraile.as development of the facial area of a human develop, the head becomes much less round (so a fetal skeleton would have a rounder head). the face also becomes more defined and features more noticable. I hope this helps.
In the fetal skeleton, the ossa coxae (hip bones) are not fully fused, and they consist of three separate bones: ilium, ischium, and pubis. In the adult skeleton, these three bones have fused together to form a single hip bone. Additionally, the acetabulum, the socket where the femur connects to the hip bone, is not fully developed in the fetal skeleton but is complete in the adult skeleton.
The appendicular skeleton has more bones than the axial skeleton. The axial skeleton includes the skull, spine, and rib cage, which have a total of 80 bones. In contrast, the appendicular skeleton includes the bones of the limbs, shoulders, and hips, totaling 126 bones.
There are more than two long bones in the skeleton but if you mean the two longest bones then the femur (longest) and tibia second longest).

the fetal bones are much more delicate than the adult

In the adult skeleton, these three bones have fused together to form a single hip bone. Additionally, the acetabulum, the socket where the femur connects to the hip bone, is not fully developed in the fetal skeleton but is complete in the adult skeleton.
The ossa coxae (containing the ililum, ishium, and pubic bones) are not fused in a fetal skeleton like in an adult human.

it is weaker

dem bones are the heaviest bones in the skeleton
basicly yes!ANS2:As the skeleton matures the growth plates at the ends of long bones fuse and sessamoidal bones, such as the patella, form. On the whole, more bones fuse than do new bones form so an adult skeleton has fewer bones than an infant's skeleton.
