Baby poop: A visual guide (via Neatorama)
This photo guide to baby poop will give you a good idea of what's normal and what's not as your newborn grows, drinks breast milk or formula, and starts eating solids. You'll find out when not to worry and when it's wise to be concerned.
As a general rule, if you see anything completely out of the ordinary in your baby's diaper, play it safe and call the doctor.
Fair warning: These are pictures of real baby poop! Please view only if you're comfortable with that. If not, you can read this description without photos instead.
