Infants 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 have been proved. For instance:

  • Colic doesn't occur more often among firstborns or formula-fed babies.
  • A breast-feeding mother's diet probably doesn't trigger colic.
  • Girls and boys — no matter what their birth order or how they're fed — experience colic in similar numbers.
