First "sentence"

Keeley has TONS of words and is quite the little mimic when you speak. However, up until today, she only puts words together that I think she believes are one word anyway (wake-up, all-gee...). Today she told the dogs to go out, opened the back door for them, waited for them to leave, closed the back door, and then said "bye-bye doggies". She then gave a satisfied nod and continued to play.
