What does normal newborn poop look like?

Mustard: Your newborn's first bowel movement, meconium, looks greenish black. Then, it can change to mustard or tan or greenish or brown. Normal poop should not look white, gray, bloody or black.

Thick mustard: After the initial black meconium thick tar-like stools, stools transition to soft, seedy, and brownish to greenish, after feeding is established, usually by 5 days old.

Yellowish: After the sticky "meconium" has pooped out of the baby, the normal newborn poops will be yellowish and be about as thick as spaghetti sauce or mustard (and should not smell too badly).

Almost anything: Initial newborn poop is usually greenish black meconium. Aftter that it can be any one of a number of colors-brown, yellow, green. It can be dark or light, firm, hard or soft, all of which can be normal. Red or bloody, tarry black or white could mean a serious problem and your pediatrician shoul be called.

Seedy yellow: The first stools of a newborn are called meconium. They are tarry, sticky and almost black. They represent sludge that has been building up in the baby´s intestine during pregnancy. After this, stools may be mostly odorless and runny, with little bits that look like mustard seeds if he is breastfed. Formula-fed babies have thicker, smellier stools.
