I take care of a little girl who just turned 1. When I let her watch her favorite cartoon, she will let me know that it is about to end. Like a minute before it ends she will waive her hands and "talk" and try to get my intention to the cartoon. While she does that she also often gets up, knowing that it is time to do something else. She has been doing this since she was 11 months. Is this normal for her age?
