Here are the list of what you need to know about infant poop.
MECONIUM: While he is still in your womb, your baby will swallow some amniotic fluid(the fluid resembling saltwater in which your baby floats) as part of normal fetal activities. After birth, he will shed the amniotic fluid during his first bowel movements. These first stool are called meconium.
BREAST FED POOP: If you are breast feeding, your baby's stools will eventually be mustard in color, seedy and runny. Some moms say that a breast fed baby poop doesn't stink or that it has a distinct smell that may be described as sweet, but still has an odor.
BOTTLE FED POOP: Formula fed babies will have soft, tan colored poop, quite firm but not firmer than the consistency of peanut butter. The odor is usually stronger than with breast fed babies, and varies with different types of formula.
SOLID FOOD POOP: As your baby grows older, he will have fewer bowel movements, and his stool become more formed and pasty. When he starts on solids, his poop will change dramatically. A lot of what he eats can be seen again in his diaper and his bowel movements can be highly irregular as his intestines learn to digest new foods. Be sure to give your little one lots of fluids.
