This is a very tricky question as you can get a lot of answers that will be partially correct.
The best answer in my oppinion is between the range of 7 minutes to around 15 minutes.
The reason why saying just one value isn'the best idea is because, if we have two groups of people, the average for the first group might be 7 minutes, and the average for the second group might be 11 minutes. So it's hard to say the average is 7 minutes. It's better presented in an interval where we can find this number :)

The cranial bones are bones that surround and protect our brain. In infants, the cranium is composed of different separate cranial bones.
- The bone that exists as five separate bones when you are an infant is the CRANIUM.
- The major bones (bony plates) that form the cranium of an infant (newborn) are 2 frontal bones, 2 parietal bones and one (1) occipital bone.
- Subsequently, bony plates are joined to each other by a fibrous joint called a suture.
