At first she was pretty dazed. We couldn't tell if it was from the colorful explosions or from being woken from a deep sleep.
Brian and I stayed really positive pointing at each flowery shower and twinkle mist saying "Look," "Oh, Pretty," and "Boom." Eventually, she timidly started pointing along with us.
Warming up (or maybe waking up) a bit more she started clapping and smiling, clutching Mona a little less tightly.
Then, all of the sudden, she sat up and started scanning the horizon.
From that point on Magnolia had a lightning fast pointer finger, and whenever there was a lull she emphatically signed for "more." There were more than a few "boo(m)s" said too and our made-up sign for fireworks caught on very quickly.
When I went to get her out of her crib this morning after a good sleep-in she immediately started signing for fireworks and urgently pointing at her window. I took her to her window, but sadly had to explain that the fireworks were "all done." Later, that afternoon I told her it was time for her nap and she signed fireworks again, as if to tell me it was okay to wake her up for them. I think she may have the idea now that fireworks happen every time she goes to bed!
