on her own

This morning when I woke up it was quiet. The girls are usually already awake and drawing or watching cartoons, so I poked my head out to check out what was going on.
Layla was sitting quietly on the couch reading a book silently to herself. She has never read on her own before, and getting her to practice reading is usually something I dread, as she fights me every step of the way. (needless to say, this was a big surprise!)
"Whatcha doing?" I asked her. "Reading my new books about horses and ponies" she tells me, and then proceeds to inform me that female foals are called fillies and male foals are called colts. "Very interesting," I tell her, "I am glad you like your new book."
I am feeling very puffy and proud about this moment, she is learning, and I am her teacher. Note to self, get more pony books.
