What can a baby do that an adult Cannot?

Do babies have all their bones?
A baby’s body has about 300 bones at birth. These eventually fuse (grow together) to form the 206 bones that adults have. Some of a baby’s bones are made entirely of a special material called cartilage (say: KAR-tel-ij). Other bones in a baby are partly made of cartilage.
At what age do bones fuse?
A skeleton in progress
The bones in the skull don’t fully fuse until ages 1 to 2. Children have more dense, elastic tissue (called cartilage) in their joints and other bony structures (such as the ribs). This allows the bones to continue to develop and grow as the child grows.
Why adults have less bones than babies?
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. New born babies have around 305 bones. A baby’s skeleton is mostly made up of cartilage.

Do females have more bones?
In the majority of populations, men have larger and stronger bone and joint surfaces, and more bone at muscle attachment sites. However, women have stronger pelvises because of their distinct ability to carry a child and experience childbirth.
