No wonder you are tired!! I went through the same thing with my daughter. It will all be much easier in a year. Just keep staying positive about the potty training, always happy happy happy. Even when she pooped on the floor, I never got negative, because I didn't want to make it a power struggle. I read a book about the potty every night for months in a very subtle way, and I had a little potty in the living room to try to encourage her...My experience with both kids is that once they get around an older child who is potty trained, daily, then they get trained quickly. Keep on keepin on Mama!!! You're doing a great job. Keep telling yourself that. When I look back on the potty training days, the smells and time spent scrubbing carpet are dim compared to my images of them learning to talk, etc.
Love and Light,
