What Causes Constipation in Babies?

Change in diet. For babies, this could mean the introduction of solids, which can be very disruptive to their digestive system. Common foods that cause constipation in babies include bananas, applesauce, baby cereal, yogurt, cheese, cooked carrots, pasta, and white bread.

Lack of fiber. Fiber, found in baby-friendly foods like sweet potatoes and prunes, makes pooping easier. Without it, stool is dryer and lighter, and therefore more apt to get stuck in the intestines.

Potty training. “Toilet training seems to be a trigger for many,” says Harrison. When toddlers start potty training and exerting their own control over bowel movements, they often withhold stool as a result.

Genetics. Constipation often affects multiple family members. Chances are, if a parent has problems with constipation, the kids will, too.

Travel. It happens to the best of us. Being in a new place can mess with a baby’s circadian rhythm and cause pooping problems.
