It is normal for the stools of the breastfed baby to be mostly liquid, with small curds that resemble cottage cheese (some say it resembles runny egg yolks). It has very little odor. Usually the baby will have a bowel movement each time he/she nurses. It may or may not sound "explosive". These liquid stools are not diarrhea. Diarrhea in the breastfed baby is rare. A baby who has diarrhea would have stools that are very frequent, usually green and full of mucus (and/or specks of blood), and almost always foul smelling.
