In the last week or two, Kiddo has finally mastered the cup. She can hold it by herself, knows how to hold it and actually get water out of it, as opposed to needing me to hold it for her. It makes helping her drink much easier.
So, when she's mostly done with her meal, I hand her her cup, and she drinks like a parched girl. Then as she finishes her meal, she carefully cradles her cup in her arm, in case she should need it again.
She always cradles the cup in her right hand, and does the bulk of her eating with her left hand. While sufficiently dexterous with both hands, she seems to prefer the left. I find this fascinating to watch her motor development.
