how she eats a peanut butter cracker

This is what she does: splits the peanut butter crackers with her fingers and eats out the peanut butter.  I caught her a few days ago with only clean crackers on her tray and I wondered where the peanut butter went.  I just witnessed it.  After handing her the crackers, she  immediately split them open and ate out the inside.  Hmmm.  Where on earth did she learn that?  She certainly didn’t learn it from Mom or Dad!  Is it human nature to split the cookie and eat out the sweet inside?!  Anyway, it’s pretty darn cute, and she’s got some serious fine motor control!
