H.,
I have a son who is now 4...and I must admit that I never really went through the whole potty training thing, as my son amazingly started training himself at 17 months. But I so remember at one point after he was completely trained when he was around 2 he decided that he didn't want to go to the potty anymore, and just did not care. That only lasted a few days...but I was just besides myself at that time. I noticed the more upset I got at him, the more he did it. When I played it off kinda cool, it was over. Back on the potty he went! I personally think that letting it go, and putting him back in diapers / pull ups would be a big mistake. He will fall into that habbit. You never want to go backwards with a child. I hope this helps you in some way. Let me know how everything works out.
