My little thinker

Alivia and I have had many conversations about the moon and sun and she understands that the sun makes it bright outside and when the sun goes away the moon comes out and that's what makes it night time. But, tonight she stumped me

Alivia: The sun is out and the moon is sleeping right mom?
Me: Right
Alivia: And when the sun goes to sleep the moon will wake up right?
Me: Right
Alivia: Does the sun wear pajamas?
Me: Um, No
Alivia: Does the sun have a house?
Me: Um, No
Alivia: Where does the sun sleep?
Me: Ummmmm
Alivia: Does the sun sleep in the clouds?
Me: YES! yes the sun sleeps in the clouds
Alivia: Where are the clouds?
Me: (looking up in the sky and noticing I can't see any clouds) We can't see them right now, they're too far away

She changed the subject after that!!!
I need to work on my reasoning! Or maybe I'll just go buy a book for every subject I can't explain!
