I forgot a couple of things...

-Spencer was saying up and down as he moved his cars up and down the ramp on his garage. The letters were off, but the tone was there and when I started saying it too he was really happy. Then I started saying up in a high pitch and down in a low pitch and he mimiced it perfectly!!!

-At the play area he responded to everything I said. EVERY TIME!! Yippee!!!

Man it was a good day!!!
