Emly is Walking!?!?!?

Tonight at Music class, Emily was watching another little boy run around the room, and I could see those wheels turning in her head.  She wanted to run around too.  Later on in the class, she was standing in front of me and she took off toward the instrument tub.  I was shocked and excited to see her finally walking around.  I decided it was time to call it... Emily's walking!  But then, Tuesday comes and goes, then Wednesday and no steps.  Does it still count?  I don't know.  What do you think?
