I'm trying to TT Imran since he seems keen on wearing underpants and going to the loo (unlike his brother who screams for his nappy if I put undies on him).
How often should I offer him the chance to use the potty?
He's about 20 months old I think... (I should look at my ticker lol)

ETA - he's hardly had his hand out of his undies since I put them on lol. If it doesn't work I'm going to have to gaffer tape his nappies on.
