We have restricted Audrey's pacie usage to night time only, although she tries her hardest to feed her addiction during the day.
Daddy: "Audrey, put your pacie away, you don't need it."
Audrey: "But I DO need it. I can't breathe without it."
Daddy: "You can't breathe? I'm sure that's not the case. In fact you can probably breathe better without it."
Audrey: "But I NEED it!"
Daddy: "Put your pacie away right now or you won't have it tonight."
Audrey: "Okay... But can I have just one more suck?"
Daddy: "Um, sure."
