Stephanie, Hi and welcome to the Toilet Teaching board.
In the beginning of training I always took two week breaks in between. Each time we started back up it was easier. We took breaks until we found the combination of methods that worked best with my oldest DS, which was the naked method with rewards charts. During the breaks my DS would occasionally ask to use use the potty, so during breaks I just followed his lead. I suggestion, I would take your DS out shopping to pick out big boy underwear to get him motivated. I hope that helps. Please keep us update don your DS progress.
