Dead tired

Tonight while I was updating my blog, Abby came in and said she was tired.  She held my thumb like she has done since day one of her life and just stood there.  I proceeded to type with one hand and I kid you not within just a few minutes she dropped to the floor.  She had fallen asleep standing up.  It wasn't even late enough to be bed time yet so I thought she just wanted to snuggle.  WOW...she was really tired.
