Stress Free Potty Training?

I had been avoiding the idea of potty training. It just made me stressed to think about all the work that would go into it. So, I looked online and found this book:
The book gives parents different signs of readiness to look for before you start potty training. A quiz helps you determine what your child's personality is, then divides the different personalities into chapters. I didn't read the whole book--just the chapters that pertained to Ryder's personality types (he's a combination, of course).
About a month ago I bought him a potty chair to get him interested in the idea.
Then I started giving him "naked time," which means that after bath time or a diaper change you let your child roam free. This helps them feel the sensation more easily.
This brings me to yesterday...I was letting Ryder have "naked time" after the bath. I even gave him a drink to help him try to go pee-pee. After nothing happening I walked out of the room for a bit, and I heard the successful sound of the potty chair. I went in to see what had happened and ta-da! A successful pee-pee. He did it again for Rocky. Then in the evening he had 2 accidents. Unfortunately one was a not-so-easy-to-clean accident. Let this potty business begin.

He decided to take his diaper off during his nap. Peek-a-booty. :)
