Why is the baby's head so big compared to the body?
Indeed, compared to adults, babies have a head that is " giant " compared to the rest of the body. The head of a newborn baby can be one quarter of the total body length, while the adult's head only accounts for about one seventh.
The reason for that, in summary, is for the brain . Although the body is small, a newborn baby has a relatively large brain compared to its size. That means they must have a large head that is enough to accommodate this brain block. It is possible that people need a large brain from birth because if it is smaller, the time for the brain to grow will be longer and slow down our own process of walking, talking and surviving. .
The longer the time for a child to serve himself / herself, the greater the effort of the parents to take care of. Imagine how much energy it takes for parents to reach 4 years old

I just started walking, instead of just 2.
Conversely, if the baby has a larger brain now, children may know to hopscotch just 1 week after birth. But that means that the child's head will be too big to pass through the mother's natural birth path.
In fact, some newborn babies have an odd-shaped head while being squeezed through the birth line. Therefore, newborn babies whose brains are just as big as they can, though the head seems a bit . out of balance.
But why the baby's head continues to look great after they are born, even when the baby is 1 year old. Again the answer is still the brain. To be able to quickly help children to be self-reliant, in the first year, the brain develops extremely rapidly. And by the time you were 1 year old, your child's brain was about two-thirds larger than an adult's brain. That means that in the first two years of life, the brain (followed by the head) continues to look oversized compared to the body because it is developing rapidly. After 2 or 3 years, the child's body begins to catch up with the brain, the head grows slower, and the child looks more " normal ".
