    Judge it by its pictures and on whether it has textures or animals in it.
  5. The early bird just gets ends up cranky before nap time.
  6. You can't make an omelet.
    Seriously - stay out of the fridge.

    It just takes a certain pitch in your whine
  9. Actions speak louder than...

  10. Easy come, never let go.
    Until the other kids are no longer interested
  11. One kids trash is another kids fortress.
  12. Don't bite the hand that feeds you.
    Or the ankle, or knee or your dog.
  13. All good things must come to an end.

  14. The pen is mightier than the upholstery.
