He'd been running around naked for quite awhile pre and post bath, covering his bottom, farting profusely, and finally announced, "I have to poop! I have to poop on the potty!"
Nelson took him into the bathroom and sat down on the toilet beside Oscar's potty, modeling potty behavior as we have been for months. But, Oscar wouldn't stay put. He kept jumping up from the potty and running around in circles shrieking.
Nelson got frustrated and thought maybe Oscar was just trying to delay bedtime (entirely possible) and told him no, no more potty, at which point Oscar burst into fat, hot tears and began wailing about his need for potty.
Then, he asked Nelson to leave the bathroom; he wanted his privacy. Oscar shut the door and we hear him saying, "There's pee-pee in there. I just gotta try. I gotta try and pee-pee. I gotta try and poop. I just gotta try and use the potty."
He popped in and out of the bathroom three or four times, and then I finally told him he needed to try one more time, then it was time for bed.
So he did.
"I just gotta try. I just gotta try an pee-pee in the potty."
He came out 30 seconds later, grinning.
"Did you do it?"
"No, there's no poop in there."
So I went to check and he wasn't lying; there was no poop.
Oh, but there was pee.
"Oscar! What is that? Did you pee-pee in the potty?"
"Yeah, Mommy. I pee-peed in the potty," he said, and then he stuck his hands in it.
