Thomas decided to keep quiet about his coming accident and let Sarah discover his boom boom like any mother, figuring that it wouldn't be too mean of him. The urge to poo his pants increasing with each passing second, far too quickly for him to even dream of making it to the toilet.
Not that he would have mind you.
Even though all it would have taken was a small push on his part to start pooping Thomas was curious to find out how long before his young toddler body would let go of it's own accord. Turns out it was a scant five seconds as that exact amount of time later he felt his mess emerge from his butt. However unlike at the transfer room this time he felt a tiny bit embarrassed due to no longer being on an emotional high from a physical regression. Regardless he was inwardly happy at soiling himself for the second time today, sucking his thumb to not make any noise as his baby muscles effortlessly pushed a semi solid mound into the back of his pamper.
Thomas smiled behind his thumb when he finished seconds later, happy at having a full diaper.

"I went poopoo" Thomas announced pretending to act the innocent boy who only now just realized he made a stinky in his pants.
"Of course you did, that's why your in diapers silly cause you're still just a baby" Sarah replied hoping she wasn't laying it on too thick. "Now don't you worry you little stinker I'm going to change you into a fresh one...for both our sakes."
Thomas giggled at that last part as he rather enjoyed pungent smell currently leaking out of his pampers, a universal sign that his diaper needed immediate changing. Such a common part of the typical baby experience and yet one he was glad to have went through.
While Thomas mused about his infantile existence Sarah carried him down the upstairs hall to his room.
However upon entering it was revealed that his room was a...
