How do I know they are ready? Do I wait for some specific signs or do I just pick a convenient week and have a go?
DS (2.5) tells me if he's doing a wee, but not always a poo, although I think he knows when he needs one. He's never seen the potty as anything other than a racing car to drive around. He shows interest in us on the loo. He doesn't have enough language yet to reliably tell me verbally if he needs it.
Is there some magic threshold when I will know its right or do I just guess?
