Birth applies compressive and rotational forces to a baby's head and cervical spine. Most babies adapt without difficulty. In some cases the process leaves enough residual tension in the upper neck to affect how freely the baby can move the jaw, with direct consequences for feeding.
Feeding and latching treatment at Beacon Clinic begins with the birth history because it often points to the origin of the restriction. Addressing that tension early, while the baby is still developing rapidly, tends to produce faster improvement than waiting.
