Oh Crap, it worked. The "Oh Crap" potty training method/ eBook, which we used to motivate us to potty train our 28 month old son, worked.
After 2 days walking around in just a t-shirt, he graduated to going commando (pants with no underwear) on Day 3. That day was the worst day. I prompted him to use the potty two times in which he sat and nothing happened, even after 5 minutes of me reading him stories (with Claire on my lap). Then I would say, "Fine I guess you don't have to go." He would jump off the potty and 3 minutes later I'd find a puddle on the floor. It was a long day and Matt was back at work so it was just me holding down the fort.
But then the grey clouds parted and sunlight broke through when -- after a 40 minute potty session in which I read
The Cat in the Hat Comes Back 7 times -- he pooped in the potty. Per the book, pooping in the potty is harder for the toddlers to do. Wesley held his poop for two days before he could relax. After this major poop hurdle, he went as prompted for the next couple of days and we had no "accidents." Even his nighttime training was a breeze. He had maybe 1-2 accidents at night, but for the most part, Matt woke him as needed to use the potty (1-2 times a night), and he was fine.
Day 6 ... Thanksgiving at my aunt's house. This was the moment of truth. We were taking him out -- a no-no per the book this early, but what could we do. Up to this point he had very few accidents and went as prompted so we felt very comfortable bringing him commando with his potty under our arms. As long as we prompted on the hour, as we did at home, we should be fine. And ... he was! In fact, for the first time he self-initiated telling Matt, "Potty! Potty!"
Day 12 was his Parents Day Out morning (pre-school). They were prepared to prompt him on the hour as I instructed and he was great - he went when asked and he came home in the same pants he went there in.
After that, the self-initiating became more and more frequent until about week 2-1/2, when I never had to prompt him again... only before we're leaving the house.
December 1st, we did the Polar Express - he went potty on the train. And the following weekend, we had our annual brunch in Lake Geneva and he even went poop at the Grand Geneva. We were so proud... of us, of course! We did it! We potty trained our son at 28-months! (A huge hurdle since our doctor said 3-years old).
So how long will our little widget need to go commando? Well, Santa is bringing him some undies in his stocking this year.
