This is how I found the little bird yesterday when I checked on her at nap time.  She covered herself up and sat right there in the corner and fell asleep.  

I think it is because she likes to frequently play THIS game:
Otherwise entitled, "let's pretend to read/sleep/hide and seek/wrestle in Mama and Daddy's bed."  Here she is reading her Golden Guide to Birds that was my grandmother's. She points at her favorites, makes a lumpy sort of noise that sounds almost entirely UNlike "bird" and then looks to us for approval while making that questioning "ueh?" noise that babies do. 
This is what I saw when I looked out my kitchen door yesterday into the garage.  I thought he was practicing building a campfire, but he claims no-just a structure.  Why they have toys, I don't know.  (If you can't tell, he's just building with sticks).
This is the quick bag I finished up for Calvin last night.  It was lovingly (ahem) dragged through the mud on his farm field trip today.  It turned out really cute, but I put it together very fast and some things were done awfully sloppily.  I was almost hoping he wouldn't want to take it..
Almost.  Secretly, it made me feel good that he wanted to carry it and even pronounced it "cool."  Although I am not certain it was anything I did.  He liked the corn.
