The Fontanelles Most importantly allow for the human skull to pass through the birth canal and are vital in allowing the brain to grow inside the skull without increasing the intercranial pressure.
Fontanels are responsible for the "soft tops" on the top and back of the head. The flexibility imparted by the fontanels allows the baby's skull to deform somewhat in order to fit through the narrow birth canal during the miracle of birth. The fontanels also enable the skull to grow large as the child grows. The gaps between the infant's cranial bones gradually shrink as the fontanels are replaced by growing bone.
Fontanels solve a major problem of vaginal birth in humans, namely large baby head passing through a space-limited vaginal opening. Fontanels allow for cranial plasticity and compression/elongation that facilitates successful deliveries.
Fontanels are cartilaginous (hyaline cartilage) connections between the bones of the skull during infancy; there are six fontanels on the skull (2 sphenoid, 2 mastoid, occipital, and frontal), and they are present to allow for growth and reformation of the infant skull. As the infant progresses into adulthood, these fontanels ultimately harden and produce the synarthrotic sutures of the adult human skull.

Your doctor knows the foetal presentation, before delivery. The fontanelles allow the head to get compressed to little extent. This much compression is of great help to the mother. As it allows for normal or vaginal delivery to take place with much lesser pain.
The fontanels allow the fetal skull to be compressed slightly during birth and also allow for brain growth during late fetal life.
To allow the skull plates on an infant to "give" and compress to squeeze through the birth canal.
fontanels are sagital sutaures and coronal sutures
Gives the babies head more flexibility as it passes through birth canal.
Allow the doctor to identified the fetal position inside the uterus at the time of the delivery, and prevent problems at the time of the vaginal delivery or the cesarean section.
