A.,
Boys don't like diapers, and potty training boys is harder than potty training girls (I have one of both so I know). My suggestion is to try pull-ups, or taining pants. He may keep these on more than diapers. It does sound like he is ready to start potty training, but make sure he is being trained and not you. I have seen so many momns being potty trained. Make sure that he goes when he feels like he has to go, do not continually pick him up and take him in. This will develop into a pattern that is harder to break than the diaper ripping off. The biggest clue as to whether he knows he has to go is when he hides somewhere when he has to go poop. This indicates that he recognizes the sensation and knows what it means. Trust me, boys are more difficult, especially for "no.2". They feel like it part of them and do not like to see it flushed down the potty. My suggestion is to boy one of the potty books. There are a lot of good titles. I think sam's club even carries one that has the sound effects of the flusing toilet. Read it to him often. Also, every kids show (blue's clues, bear in the big blue house, etc.) has a potty episode for just such an occasion. Order one and have him watch it often. These two things really helped my son. Especially with the peeing.
Good luck.
