And then - MAN are you in another realm altogether! And that can come in colors, too. Like the time black tar came out of my baby's ass. That was fun. Still in the maternity ward and he was just quite a few hours old. They rolled him in, in one of those itty bitty rolling beds that could park by my bed, so I could have him in my room with me. One of my girlfriends came to visit and I was going to change his diaper. So I got to work and as I did, this BIG black tar bubble emitted from his little - er - backside. We looked at each other in horror! Didn't know WTF that was. Turns out he was expelling the last of the meconium inside him, left over from ingesting whatever was in there while he was developing. As I subsequently discovered, "meconium is the first stool (bowel movement) that a newborn has." But SHIT!!!! If you're not prepared for that, and it starts oozing outta there, your eyeballs almost fall out of your face!
Meconium is the earliest stool of a mammalian infant. Unlike later feces, meconium is composed of materials ingested during the time the infant spends in the uterus.
