DD is now 26 months and starts pulling at her nappies. We have a potty and tell her that if she wants a wee or a poo she could tell us and then we can take her to the potty. I talk to her when I have a wee or poo and sometimes get her to sit on the potty just so she can copy Mummy. (Only a parent could have this conversation). We also let her sit on it when she goes to the bath. When is it good to say no to nappies and start get some pants. Is there a key step ?
