We had a go at this when James was just under 3 & it just wasn't a happening thing, I was nearly tearing my hair out at the frustration of it all. He understood what he had to do just couldn't be bothered. So after many discussions with my mum & my MIL we decided to let him go back in nappies for a bit & then try again. 8wks later of his own accord we found him sitting on his potty doing wees & from there on in it has been a breeze.

But as such I don't think we had a "lightbulb" moment over it.
