How do i tell my mum that i like to wear nappies?

Since you didnt say how old you are the best way to go about it is to sit and have a good talk with her. you also didnt say wether it was a blader issue, a security issue or a sexual thing. if it was a blader issue i should tell her that you wet the bed e.c.t and hope that she suggests you wearing nappies. if it is a sexual thing then im not sure. it you have a young brother or sister you could pinch some of theres, if not wait until your parents are out then go out and buy some and find a place to hide them.
