Infant Colic: A Signal the Modern World Isn’t Designed to Receive
Colic — intense, inconsolable crying in an otherwise healthy infant, typically occurring in the late afternoon and evening, lasting more than 3 hours a day for more than 3 days a week — affects between 10 and 40% of infants globally. It peaks at around 6 weeks of age and typically resolves by 3–4 months.
It is one of the most distressing experiences for new parents. It is also one of the least well-understood conditions in paediatrics — because conventional medicine looks primarily for digestive causes in what may be primarily a neurological and evolutionary phenomenon.
The Evolutionary Communication Framework
Why would evolution maintain a behaviour pattern — intense, persistent crying — that is so costly in terms of parental stress and infant energy? Because in ancestral human environments, it was extraordinarily effective.
Infant crying activates the caregiving system in adults with urgent, almost irresistible force. It mobilises not just the mother but the entire nearby social group — other adults, older children, grandmothers — into a coordinated support response. In small-band environments where the survival of the infant depended on this support, the most urgent cry generated the most support.
Evolutionary medicine researchers have proposed that colic-level crying represents an ancient signalling pattern that escalates when:
- The infant’s nervous system is dysregulated (through birth stress, maternal cortisol, gut immaturity)
- The caregiving environment is insufficient (single caregiver, isolated mother, high parental stress)
- The expected sensory environment is absent (constant carrying, skin contact, motion — the ancestral norm that modern sleep arrangements don’t provide)
The Neurological Dimension
Beyond the evolutionary communication framework, there is a structural neurological component to colic that cranial osteopathy directly addresses.
The vagus nerve — the primary regulator of gut motility, respiratory function, and the parasympathetic “rest and digest” state — runs through the jugular foramen in the cranial base. Birth compression, particularly in the occiput and temporal bones, can create restriction in this foramen that alters vagal function.
Reduced vagal tone in infants produces: reduced gut motility (gas retention), increased heart rate variability (more cry-prone), and reduced parasympathetic self-calming capacity — exactly the profile of a colicky infant.
OQ’s Approach
Dr. Sakata’s specialisation in infant cranial osteopathy is directly relevant to colic. Gentle assessment and treatment of cranial base mechanics, vagal function, and the fascial patterns of birth compression can produce rapid and often dramatic improvement in colicky infants.
Many parents describe sessions that begin with a distressed infant and end with the first extended period of calm the baby (and they) have experienced in weeks.
FAQ
Is colic always a digestive problem?
Gut immaturity contributes to gas and discomfort. But the neurological component — reduced vagal tone affecting gut motility and self-regulation — is often primary. Treating gas without addressing the nervous system gives incomplete results.
At what age can cranial osteopathy be started for colic?
From the first days of life. Earlier is generally better — the earlier structural tensions are addressed, the less they become compensated habits. Many parents bring infants within the first two weeks.
How many sessions does colic treatment typically take?
Many cases respond significantly within 1–3 sessions. Cases with more complex birth history or structural patterns may require more. Improvement is usually apparent within the first week after the first treatment.
