When you think of a baby you probably think of an adorable, tiny human being with plenty of room for development.
A relatively surprising fact is that Babies have about 300 bones, compared to 206 in adult humans.according to the medical information website Healthline.
It seems crazy that an individual of such small size has almost 100 more bones than an adult, but there is a scientific and biological explanation for this.

Bones are made of different tissues, such as the periosteum, a layer of compact bone, another spongy tissue, and bone marrow, which is the gelatinous core that produces blood cells.
This process of ossification or bone development begins in the 8th week of embryonic development.and it changes over the years, so that these living tissues accumulate and are discarded.
At birth, a large percentage of a baby’s bones are made of a very flexible connective tissue called cartilage, but as the baby grows, it is replaced by real bone.

Besides, Many of the bones will eventually fuse, causing a decrease in number, hence adults have fewer bones than babies.
This process occurs throughout the body, including the skull. That’s why sometimes when you touch a newborn’s head you notice a kind of soft spot.
These soft parts or spaces are called fontanelles and eventually disappear due to the union of bones.

The fusion process occurs when capillaries or blood vessels begin to carry blood with nutrients to bone cells called osteoblasts.
Osteoblasts are responsible for creating bone by replacing cartilage.
After this explanation, it probably doesn’t seem so surprising to you that babies have about 100 more bones than adults. That’s why it’s important to take care of your bones so that they grow healthy and strong from a young age.
