It was cold turkey here DD. 3 days at home. When he started to wee, 'd pick him up and rush to the toilet saying "quick quick you need to wee". Same for poo. Day 2 was 50/50, day 3 no accidents. Did night at the same time. Nothing's 100% and poo's taken a LOT longer, but there's less confusion for them if they don't have a nappy. Also our method involved "tell me if you want to wee" rather than "do you want to wee". Shows trust in the child. "Tell me" can be a grab and a run, not necessarily verbal - although a sign is a good idea!

I used the potty train in 3 days method and loved the exhausting thing!
