Is Tommy Potty Trained?

I am afraid to utter the words out loud, afraid that I might somehow curse the blessed event. But Tommy has not had an accident for a week, NOT ONE! and he slept thru the night last night without a diaper. I am so excited, he pees in the potty at home, at church, at grandmas, at Candise's, at stores...could this be the real thing. I'm pretty sure he only decided to be potty trained because after 7 long months I finally bought a potty-training book, it arrived on Monday. Of course.
