My son took off his diaper during the night in his crib (only wearing a big night shirt...BY THE WAY.... NOT A GOOD IDEA...I had to learn this the hard way) and he smeared his poop all over and ate a lot of it! I had a dr. apt the same morning and asked what to do. He said it is totally normal and would not harm him at all. It is his own waste. Children eat it because it seems to be something like food and smells somewhat like a food item and sometimes food is seen in it. I would guess that your son didn't want it on him and it seemed like the logical thing to do. My son now tells me that he pooped or is going to because he does not want it on him at all. I also would not make a big deal out of it and move toward the potty training maybe! Good luck-
