S.D.
My son was almost 4 when we finally potty trained him too. This is what we did. I took 2 weeks off from work thinking it would take that long to potty train my son. You are going to think I am crazy, but this is my 4th child and I was sick of changing diapers. I hid the diapers and pull ups. I told my son that we were out of diapers and pull ups and he was going to have to wear big boy underwear. He had 8 accidents the first day, 5 accidents the second day, and 0 accidents the third day. I didn't make a big deal out of it when he had an accident, I just changed him and put on more underwear. At the end of the first day I had to wash all of his underwear to have them for the next day. He still wears a pull up at night and naptime. If I don't keep them hidden he will change out of the underwear and put on a pull up, so they are hidden all the time. If he knows enough to change into a pull up himself he knows enough to go to the bathroom in the potty. It took 3 days and he was trained!
