Infant colic is a common yet distressing condition defined by recurrent, prolonged periods of crying or fussiness in an otherwise healthy baby. It typically appears within the first few weeks of life and peaks around 6–8 weeks, often improving by 3–4 months of age.
The most widely used definition — known as the “Rule of Threes” — describes colic as crying for more than three hours per day, more than three days per week, for at least three weeks.
Colic affects an estimated 15–25% of infants, regardless of feeding method, gender, or socioeconomic background. Although benign and self-limiting, it can cause significant parental stress and fatigue, and may impact early bonding and family wellbeing.
The precise cause remains unclear, but several interacting mechanisms are believed to play a role, including immature digestion, altered gut microbiota, increased intestinal gas, visceral hypersensitivity, and autonomic imbalance.
Intense, inconsolable crying or screaming episodes, often in the late afternoon or evening.
The baby may pull up its legs, clench fists, and appear to have abdominal discomfort.
Facial flushing, tense abdomen, or arching of the back during crying bouts.
Crying often starts suddenly and stops just as suddenly, sometimes followed by sleep or passing gas.
Although colic is harmless, it can be emotionally overwhelming for parents. Sleep deprivation and feelings of helplessness are common, underscoring the importance of reassurance and support.
Red flags: Persistent vomiting, poor feeding, fever, lethargy, or failure to gain weight may indicate another underlying medical issue and require pediatric evaluation.
The cause of colic is multifactorial. Research suggests contributions from:
Gastrointestinal factors: delayed gastric emptying, gas accumulation, gut dysbiosis, or milk protein intolerance.
Neurodevelopmental and autonomic factors: immaturity of the enteric nervous system and dysregulation of the vagus nerve.
Psychosocial aspects: infant temperament and parental stress may influence the baby’s regulation and crying patterns.
Mechanical and birth-related factors: strain during delivery, restricted mobility in the diaphragm, thoracic, or cervical regions may affect digestion, breathing, and vagal tone.
Osteopathic practitioners view colic not as a single disease, but as a sign of physiological imbalance in a developing infant. The focus is on supporting optimal function across the musculoskeletal, visceral, and autonomic systems.
An osteopathic assessment may include:
Evaluating spinal, cranial, and diaphragmatic motion, as well as tension patterns from birth.
Gentle, non-invasive manual techniques to ease strain and support nervous system regulation and digestive motility.
Guidance for parents on feeding posture, handling, and calming strategies — always within the scope of osteopathic care and in collaboration with healthcare professionals.
The goal is not to “cure” colic, but to help improve the baby’s comfort and promote better regulation through restoring balance and mobility where restrictions are found.
Evidence on osteopathic and manual therapy for infant colic is growing but remains mixed due to variations in study design and methodology.
Several systematic reviews suggest potential benefits in reducing crying time and improving parental satisfaction, though results are not uniform. Importantly, safety profiles of gentle manual techniques in infants are reported as favorable when performed by qualified practitioners.
