Then they really should have. My niece was over tonight she just turned 4. I was talking to my brother in law when I heard her say chicky has cracker. Well without me knowing it she threw in a cheese nip cracker. It was kinda cute watching the keep away game. But like a mean old dad I ended the game by taking it away. I dont know if she threw anymore in before I seen that one. I wasnt too worried about her reaching in and grabbing one because the lid was on.
