We're sure that Natalie now knows at least 6 words (definitely more, but these we're pretty confident about). They are: ba-ba or BAAA! (when she wants her daddy), and mm-mma (for me, which is sweet), buh-buh-buh (for all round shaped object including balls and balloons), woah-woah (for dog and other furry, four-legged animals), bur (for birds), and beh-beh (for babies). She also knows the sign language for "milk", "bye-bye", "hi!", and "more".
She is so excited to be able to communicate and, now that's she more mobile and expressive, her personality is really coming out. Yesterday, while at the driving range, Natalie spent most of her time standing and crouching (ok, squatting) next the ball buckets and was busy moving balls one at time from this bucket to that bucket. When she accidentally dropped a ball and it rolled away, she would stand, point, and yell "buh-buh!" and her daddy, me, Marian or Vivian would fetch it and it give it back to her and she was satisfied that all her balls were in place and safely in a bucket.
Then, she raised her head and looked out onto the field and suddenly realized that all those dots out on the green field we ALL BALLS. She got very worked up. She was pointing and waving and screaming "buh-buh-buuuuuh!" but of course, there was nothing we could do and we had to explain to her that we had to leave the balls out on the field. Eventually she understood and calmed down.
Here are photos of her busily "organizing" the balls in their buckets.
