Whether a baby with bad breath can take cod liver oil usually depends on the underlying cause of the odor. If the bad breath is due to oral ulcers, taking cod liver oil is generally acceptable, as it helps supplement essential micronutrients, promotes healing of the ulcerated areas, and improves bad breath symptoms. However, if the baby's bad breath is caused by indigestion, cod liver oil should generally be avoided, as it may increase digestive burden and worsen the bad breath.
