Head moulding. Although, head moulding is common in any vaginal delivery, for a primigravid, which is having a child for the first time, is much more significant. The bones of a neonate are soft, flexible, and present gaps between them. These gaps and softness of the bones allow the moulding of the head when going through the vaginal canal. Being the first birth the vaginal canal is tighter and does not dilactate so well leading to a more significant head moulding.
