"Because I Said So"

Well it has happened - I have started using the dreaded parental words - "Because I Said So!" I now know why they are used so frequently because I just can't help myself - I have run out of other things to say! The story: Haylie's newest favorite response to anything and everything I say is " WHY?" This has been going on for about the past month (I keep forgetting to include it in "The Little Things" - not sure how...)

Some examples:

M: "It's time to go to bed." H:"Why?
M: "Can you give James a toy?" H: "Why?"
M: "OK, let's get in the car so we can go to the park." H: "Why?"
M: "Do you want ice cream?" H: "Why?"

A typical conversation goes like this:

M: It's time to eat dinner"
H: "Why?"
M: "Because you said you were hungry."
H: "Why?"
M: "Because you haven't eaten in a little while."
H: "Why?"
M: "Because you just woke up from your nap."
H: "Why?"
M: "Because you needed to get some rest."
H: "Why?"
M: "Because we went to the park this morning."
H: "Why?"
M: "Because we wanted to go have fun."
H: "Why?"

So the next response.... (How many times would you be able answer the question "why?" before resorting to one of the following fallback responses):

-"Because I said so"
-"Don't ask me why anymore"
-"That's enough"
-"Because God made it that way" (this is Micah's good-natured response, although I have tried it and it usually prompts another "Why?" which could lead to many more answers and many more Why's, unless I follow it by one of the other fallback responses listed above.)

Sidebar:

In the car we like to sing "Old McDonald Had a Farm." When Haylie runs out of animals we move onto people. When we get to Haylie we sing the following (and she loves it!!):

"Old McDonald had a farm, EIEIO. And on this farm he had a Haylie, EIEIO. With a WHY WHY here and WHY WHY there, here a WHY, there a WHY, everywhere a WHY WHY WHY WHY..."

M: "Smile for Mommy." H: "WHY???"
