OMG EWWW! My toddler just tried to eat his own poop?! Is this normal?!?

He's just a curious little boy. It's totally normal for him to put any and everything in his mouth. I would introduce him to the potty. Don't expect much yet, just reward him if he does well. Don't let him play with his potty, but do let him sit on it, and maybe read him a little story.
