My dd is 25 months old and she goes to potty for pee and poo whenever the urge hits her when she isn't wearing anything on her bottom at home. I think this is already fantastic but whenever I put nappies, normal panties or trousers on she just does it inside. How can I teach her to ask me when she wants to go peepee and poopoo so that she doesn't have to wear nappy whenever we go out and then she could be nappy free for at least the whole daytime??
