Because potty training was so (ahem) challenging for all of us the first time around, we are simply not discouraging Big in his nascent interest in "the potty" and his more urgent interest in all-things-not-toddler (including booster seats in the car and not wearing diapers).
As I previously posted, once he acquired the word "PEW-OOP!", he let us know that he clearly has an awareness of from WHERE it comes and, recently, has been announcing pending BMs. Following his lead, I pulled out the old potty and the corresponding book that discusses what one does with the potty which we perused, delightfully, together.
Tonight, after taking a bath, we were playing trains and I was attempting to cajole him into his diaper and pajamas. At one point, I noticed that look in his eyes and asked him if he needed to go "PEW-OOP". He immediately got up and ran into the bathroom, me bumbling to my feet and racing behind. Once in the bathroom, he backed into the potty and I sat opposite him on our own, larger version for approximately 0.3 seconds after which he hopped up and then ran back into the playroom, looking back over his shoulder at me as if to say "Aren't you coming???"
Once back with the trains, Cousin called, and in the time it took to say "hello", Big had kneeled on the carpet and released his bowles. Let me clarify: released his bowles on the floor. I should have photographed for you all to see for yourselves. At least it was adult-like in form and substance (read: easy to pick up). This turd, sitting on the rug as it did, as if just asking for Big to absentmindedly turn his heel into it, may literally haunt me like those of the protagonist's Parkinson's-suffering dad, Alfred Lambert, in Jonathan Franzen's The Corrections.
By the time I carefully wrapped it into the clean diaper that had been intended for him and toted it to the toilet, gave him an encouraging "high five" (keeping in mind the potty-training mantra to 'keep it positive'), and tried again to wheedle him into the diaper, he leaned over and peed all over the floor.
Wish us, and our house, luck.
