Sam is clearly right handed. It surprises me, because my experience with Jack is so different. Whereas Sam already has a strong preference for holding toys, waving and dancing, and eating with his right hand, Jack STILL hasn't decided.
The pediatrician says it's unusual at this age, but not a problem. I wonder if he's truly ambidextrous, or if he prefers left but tries to copy others by using his right.
Lately we are working on writing. I think he has better results when he uses his right hand. Maybe he's just confused? It's funny to watch him change hands.
