Why are the fontanels important during childbirth?

Fontanels, or soft spots on a baby's skull, are crucial during childbirth as they allow the baby's head to compress and reshape as it passes through the birth canal. This flexibility helps facilitate a smoother delivery, reducing the risk of injury to both the mother and the baby. Additionally, fontanels provide space for the rapid growth of the baby's brain during the early months of life. Their presence is essential for accommodating the significant changes that occur during birth and early development.
