My 3 yr old Reagan has been completely toilet trained for over a month. He has had no problem going pee anywhere and he generally poops at home. This last week he has "forgotten" how to poop in the toilet! We are going through 2-3 pairs of underwear a day! It is very frustrating

and I am getting very grouchy, so is dh. We do the talk with him about where he needs to go and that is is gross to go in his pants. He will tell us that he should go in the toilet, but then a couple of hours later he has gone in his underwear again. If anyone has ideas on how to get him to go back to pooping in the toilet, that would be greatly appreciated.
