I also used the "oh crap" method with success. I definitely recommend reading it before you start - preparedness on your part will help ensure success for your LO. I started my son at 23 months. I had my son naked at home for 3 days, commando for 3 weeks, then went to underwear. I was lucky and never had to night train and he started dry through all his naps. 3 months later and he's only had a handful of accidents - pee only because he's been too distracted playing to bother going to the bathroom. Good luck!
