Seriously?

So Aspen just woke me from a dead sleep SCREAMING! So of course I jump out of bed and run into her room to see what's going on? Is her leg stuck? Did she climb out of her crib and land on her head? In the 2 seconds it took me to get in there, I had lots of terrible visions of some sort of injury -- because she was SCREAMING like there was something terribly wrong. So I get into her room and she's standing in her crib holding her arms up for me to pick her up, so I do and she snuggles into me for a minute or so and then she lifts her head up and starts signing "more." Now, Aspen signs "more" for many things...so I start asking what she wants more of...she has her sippy full of water in her crib, so she's not thirsty. Is she hungry? I ask her, she shakes her head. No food needed. Then she is crying and signing "more, more, more." Then she says "MOM!" and signs book to me. Woah....wait a second? There is no possible way that my child, who sleeps so wonderfully for 12 hours each night, has woken up because she wants to read....no way. But she keeps signing more and book and so I ask, very tentatively, "Do you want to read a book?" and she nods her head yes and smiles! Seriously?!?! Seriously? She seriously just woke up at midnight-thirty so I would read her a book? Yeah, seriously. We went in the living room and snuggled up in a big fleece blanket and read two books - 3 times each. Then she went back to sleep so soundly. Wow.
