DD2 wont keep her nappiesd on, cloth or disposable. She wants to wear undies like her sister. So I got the potty out and I put the seat on the loo which she is happy to sit on but wont do anything. When she needs to wee or poo she goes and grabs a nappy for me to put on her. I try gtting her to sit on the potty or loo but she wont go.

What should I do, persist with her without the nappies, hide them so she can't go grab them and keep putting her on the potty/loo.

Or do I just persist with putting the nappies back on her everytime she takes them off.

DD1 was very easy to TT but DD2 seems to just want to copy but not actually do it. Is what she is doing still a sign to start?

I am a bit confused.
