You need to enforce the concequences

Tonight Cinderella overheard me talking to the hubs.  I had an idea of making a reading corner, where there is a bookcase for the kids, and maybe some bean bag chairs.  Cinderella loved my idea and started sharing her input.  I then told her that I am concerned that things like bean bag chairs would just become something the kids played with, instead of just sitting in them, and they would get ruined.

She then told me, "make a rule, and enforce the consequences.  We have all these rules, with consequences, but you don't enforce them, so the kids don't know they are doing anything wrong."

Oh how wise an 8 year old can be.
