Doctors now believe that colic is rarely, if ever, caused by a milk allergy. After all, breast-fed babies also get colic. They also believe that colic is probably not caused by gas. It may be hard to tell which came first, the gas or the colic, but they suggest that more often than not, a colicky baby has developed gas by swallowing too much air during crying spells. Prescribing anti-gas drops has not proven to be a very effective way to treat colic, although it does seem to help some babies.
Some doctors think that colic is due to the baby's own temperament.
Some babies just take a little bit longer to get adjusted to the world, or a day and night cycle. This is perfectly normal, and the colic will go away. There is no single treatment that always gives relief to infants with colic, but there are some things you can do for your colicky baby that may make life easier for both of you. First, make sure your baby is not hungry. If he isn't, don't continue trying to feed him.
