Tuesday's random questions...

How do babies know that it has been 3 hours and it is now time to eat again? Do they have some sort of internal alarm clock that goes off every 3 hours? They are fine at 2 hours and 59 minutes but when it hits 3 hours the screaming begins. Why do babies ALWAYS poop in clean diapers? Why can't they do all of their business in the dirty diaper that they are wearing rather than mess up the clean diaper that I just put on?

Have you seen this??
