A1.6.4 Infantile colic

Excessive, frequent crying in a baby who appears to be otherwise healthy and well fed.

Diagnostic criteria:
A. Recurrent episodes of irritability, fussing or crying from birth to 4 months of age, fulfilling criterion B
B. Both of the following:

    1. episodes last for ≥3 hr per day
    2. episodes occur on ≥3 days per week for ≥3 weeks

C. Not attributed to another disorder.

Infantile colic affects one baby in five, but failure to thrive needs to be excluded.

Infants with colic have a higher likelihood of developing 1.1 Migraine without aura or 1.2 Migraine with aura later in life. Mothers with 1. Migraine have been found to be 2.5 times more likely to have infants with colic than mothers without. For fathers with 1. Migraine, the likelihood of an infant with colic was increased two-fold.
