Finger pointing - Not the middle one

One day, we saw Small E was pointing with her little index finger. We thought that it was just fun or she was just raising it.

As the days passed, we realised we were wrong. She started to finger pointing us the things she wanted. I decided to do a test for her.

Scenerio:
Small E: Pointing to the car toy
Me: Took another toy and gave her.
Small E: Continued pointing to the car.
Me: Gave her another toy next to it.
Small E: Still pointing.
Me: Finally gave her the car.
Small E: Gave me a big smile.

Now, she added sound effects when she did her finger pointing. The "ah", "eh".. etc.

Just hope she will not be using the middle one when she grew up.
