I am a bit worried about leaving the door open for DD when we start toilet training. She is the type of kid that would open the fridge and start making herself something to eat (read make a huge mess) if she is left on her own, even at 4 am . I know we can child proof a lot of thing but we rent and there are still things we can't change. I am more concerned about her safety.

Is it okay to have a potty in her room vs leaving her door open?
