throwing stuff

Chantel has learnt to 'let go' stuff. Whenever we played ball with her, she could not let go of the ball but have to come to us and hand us the ball.
We also have a toy (from HP) which is like a ball and if we hit the ball (or dropped) the ball lights up and looks cool to see. C could never "drop" the ball and had to smash it onto the computer CPU (or any other hard surface) to light it up. Nowadays, she understands throwing and can drop the ball and laugh at the rolling lighted ball.
(Even though this 'sense of throwing' is new to her, she NEVER had any problems chucking (pushing / pulling) stuff from the cabinet / table and flooring it perfectly!!
