sporty, same here. I am not really bother by potty training. I still remember how my son is toilet trained. He has this redness on his urinal part when he is around 20 months. He said it is very painful. So I told him, if he wanted the pain to go away, then he cannot wear pampers anymore. He need to tell me when he wanted to do business. Of course I don't depend on him. I bring him to toilet every 45 minutes. Just 2 days of training, he is able to tell us accurately when he need to go toilet. Of course there are accident along the way, very very rarely in the first month. He would pee on the floor. He would give us that guilty and worried look. We just told him there is no worries, just an easy clean up. Just need to tell us earlier. Luckily he always give us the right message when he wanted to do big business.
Of course, there are other children who are toilet train later. Even at 3 or 4 years old.
