Been potty training DS1 for a while (2 yrs 5 months). Basically, he knows what to do. For about 2 weeks we had no accidents at all and was doing really well. Anyway, on Friday I introduced the concept of a toilet. He ran away saying "I don't want to" and since then he has started weeing everywhere except on his potty. On friday it was just on the floor and was only once, same on saturday, sunday no accidents, but today he has weed himself on the sofa twice.
What do I do?
