Normal expansion of the skull occurs with the growth of the brain, a babies brain will grow 60% in the first year. The normal shape of a babys’ head should be symmetrical without excessive molding. Factors that can influence head shape include misalignment of the upper neck joints and the cranial bones.
Misalignment of the upper neck during birth may result in the baby only being able to turn their head in one direction and/or sleep in one position. This can cause the base of the skull to flatten on one side.
Cranial bones which have been traumatized in the birth process, especially with the use of ventouse suction or forceps, or have been constrained in the utero, are subject to locking and are therefore unable to float freely. This does not allow the brain to expand the cranial bones and results in asymmetry of both the cranial and facial bones.
Both of these situations respond very well to chiropractic care, and should be monitored as a child grows so as to avoid future spinal problems such as scoliosis.
