Understanding Baby Poop Colors
New parents often worry about their baby's diaper contents - and for good reason. Stool color can provide valuable clues about your baby's digestion and health. The good news? Most colors are completely normal, especially in the first weeks as your baby's digestive system matures.
The First Week: What to Expect
Your newborn's first stools (meconium) will be black and tarry - this is completely normal and clears material from the womb. Over days 3-5, you'll see transitional dark green stools. By the end of the first week, breastfed babies typically have yellow, seedy stools while formula-fed babies have tan or brown stools.
Colors That Need Immediate Attention
While most colors are normal, white, grey, or chalky stools always require immediate medical evaluation as they can indicate liver or gallbladder problems. Similarly, significant blood in the stool or black tarry stools after the newborn period need prompt attention. When in doubt, save the diaper and call your pediatrician.
