This is rather common. I would try having him clean up the messes (you can clean up after him of course). You can try doing whatever you did the first time you trained if you really think he has regressed that much (like back to whatever small rewards you used, etc). Also if he's too distracted by whatever he's doing to stop to use the potty, you can take away the thing (toy, dvd) he was distracted by until he has x number of days/hours of no accidents. With my daughter, she had a couple of these regressions in the six months following training... I can tell you she always did get back on track, but sometimes it wasn't totally clear to me either why things went haywire or why they clicked back into place. I think sometimes they have these regressions when they're making developments in other totally un-related areas. Just avoid at all costs the temptation to put him in a diaper! Good luck!
