I understand better after your responce. For the next couple weeks try exclaiming "oh! I need to go potty" so he has an idea that there is a pre-emptive feeling. Use the word need and maybe look for opportunities to show the difference between -need- and -want-. About 15 mins after he eats ask if he would like to "see if he needs" to go instead of "try". Also check the timing of his bm's and check for consistancy so you can know when to encourage him. Good luck to you!
