Why does an 18-month-old baby have black stools?
⚡ Short answer: In an 18-month-old, tar-like black, sticky, foul-smelling stools may indicate bleeding from the upper digestive system and require a visit to the pediatrician the same day; iron supplements or certain foods can also darken stools, but you shouldn't overlook the difference in consistency and odor.

Why does my 18-month-old baby have black stools? My mother-in-law says one thing, but I'm reading something different.

In a baby over 3 months old, black stool—what doctors call "melena," which looks like tar, is sticky and has a bad odor—is usually a sign of bleeding from the upper digestive system (stomach or esophagus) and requires a pediatrician visit the same day.
However, you might be confusing it with dark green-brown: iron supplements, blueberries, beets, and other foods can make stool very dark. The key detail doctors look for that you might be missing: consistency and odor. Bleeding-related black stool is thin, tar-like, and has an uncomfortable smell; food-related darkening is usually normal in texture.
Here's what to check: is there bright red blood visible in the diaper or underwear? Is your baby fussy, pale, or losing appetite? If these signs go with it, don't waste time—see your pediatrician. If not, it's still best not to wait—have a doctor look at it rather than "wait and see." Waiting can be risky.
Health-wise, this will get sorted out.
