Unintegrated, active primitive reflexes may be caused by:

• Stress of the mother and/or baby during pregnancy; breech birth, birth trauma, caesarean birth, induced birth
• Lack of proper movement in infancy: being placed in baby walkers/rings, jumpers, being left for long periods of time in car seats/baby capsules, and being placed in front of TV in bouncers all restrict critical movements required for brain development
• Illness, trauma, injury, chronic stress
• Environmental toxins, complications with vaccinations
• Dietary imbalances or sensitivities

Reflexes that are inhibited and integrated in infancy can later reactivate because of trauma, injury, toxins and stress.
