It's "potty" time

Matthew pooped in the potty this past week. One little specimen about the size of two raisins squished together. I was so pleased and tried to be supportive by praising him. He wasn't exactly sure what was going on, saw this in the potty and picked it up to examine it. I responded by saying, "That's poop." He shrieked and dropped it back in the potty. Then wouldn't go near the potty until I had retrieved it with some tissue and dropped it in the big potty.
