loopy - We had head lice in feb when my twins did their potty training, so we had to stay in for 2 weeks, but saying that, I never went back once they were in pants, and after the 2 weeks, just went on potty before the school run! or before going out! and if we were going to be out for over an hour then I would take potty with me (can get disposable potties though if not practical for you)
Sorry I havent had any problems whatsoever with all 3 of my children, so I'm not a good example for problems, oh sorry I do remember my ds (10yo now) but I did put pull-ups on him when he was on his holidays (he chose to potty train then)! but we were out for long periods of time then! but he was ok, never even wet them.
All kiddies are so different, they are ready when they are ready, on average around 2.6 when they start to show serious signs of trying, but mine were nearly dry at night, so that was the best indication I personally had that the twins were ready.
Don't worry though, everything else is a nightmare, we are the most disfunctional family on earth, I was just lucky with the potty training!
