I'm trying to teach my four year old to shoot a bow. He uses his right hand for most of the things that he does so he is shooting a right hand bow. Although he is still some what erratic, I have noticed a definite tendency to group the arrows to the left of the bullseye. After testing him, I found out he is left eye dominant. What should I do? Do I need to buy him a left hand bow? Should I have hime close his left eye? Are there any other solutions?

Thanks
