Overfeeding a baby often results in discomfort from not being able to digest all of the breast milk or formula properly. Although crying from discomfort is not colic, it can make crying more frequent and more intense in an already colicky baby. When fed too much, a baby may also swallow air, which can produce gas, increase discomfort in the belly, and lead to more crying. An overfed baby also may spit up more than usual and have loose stools.

The amount of food each baby needs varies. Young babies usually do not take more breast milk or formula than they need. In general, your baby should seem healthy and happy and have good muscle tone, healthy skin, and good colour. Call your doctor if you have any concerns.
