Many of these babies will also have an intolerance to soy protein and usually need to be on an elemental formula, such as Nutramagen or Alimentum.
Breast fed babies can also develop allergic colitis, usually secondary to maternal milk drinking. Eliminating milk and other dairy products from the mother's diet is usually necessary, but you can continue to breast feed.
Babies with allergic colitis should be seen by their doctor, especially if they have poor weight gain, vomiting, or abdominal pain.
Infants with allergic colitis will be normal except for having small bright red streaks of blood in their stool. It is usually caused by a protein intolerance.
