An Arm or a Leg?

I woke up to hear Spencer playing and singing in his crib the other morning. I checked the camera and saw this:

Hmm, is that an arm or a leg sticking out from under the pillow? I kept watching and saw this next:

Ok, so it was a leg. Why is he completely under the pillow though?

When it comes to Spencer, there is no point in even asking, “Why?” I love that crazy, crazy boy!
