Dd is 20 months. I have been putting her on potty since she could sit up in the hope of avoiding the fear factor later, and it was just 'luck' but she was happy to sit and deliberately produced both poo and wee. Progress had been zero, but that was obviously ok and in line with expectations
. She seems to be saying 'poo poo' when she needs a wee or poo. Today she got a bit cross when she was out and had to wee in her nappy. I'm just not ready, I was hoping she'd start this around 2 or just past like my other one.
Does anyone honestly train them at that age? Whatever gina ford/ grandmothers generation (who didn't have cars or go out that much) might think, is it even possible? 
I suppose I could use pull ups but I really dislike disposable nappies.....
