Hi, Welcome to the HCM During infancy, you may observe different shades of poops and variable frequencies. There s a wide variety of normal pooping behavior among babies: Some poop after every meal and some only once or twice a week. What s most important is that your baby s poop is coming out reasonably soft. Once you start changing your baby s input to solid foods – rice cereal, pureed bananas, and so on – you ll almost instantly notice a change in her output, especially if she s breastfed. Green poops are usually due to increased lactogen and sugars in diet. As a general rule, if you see anything completely out of the ordinary in your baby s diaper, call the doctor. There are several variations on poop that suggest a serious problem: -Thick black poop made up mostly of digested blood (called melena). It s dark and tarry like meconium but a bit firmer and less sticky. -Poop consisting almost entirely of red blood, known as currant jelly poop, which indicates a severe intestinal problem. - Persistent Pale, chalky, clay-colored poop (acholic poop) that signals liver or gallbladder failure. It looks and feels similar to tan or whitish clay or Play-Doh.
