By Mayo Clinic staffInfants of mothers who smoke during pregnancy or after delivery have a greater risk of developing colic.
Many other theories about what makes a child more susceptible to colic have been proposed, but none has been proved. Colic doesn't occur more often among firstborns or formula-fed babies. A breast-feeding mother's diet isn't likely to trigger colic. Girls and boys — no matter what their birth order or how they're fed — experience colic in similar numbers.
