I agree. Try your best to get him shooting right handed. I'm left eye dominate and shoot both trad. and compound bows right handed. I shoot with both eyes open, except in low light. But, I wish I would have had someone to catch this early on. You're a lot better off shooting the same as your dominate eye. Try turning the poundage down as much as you can until he can draw the bow. Once he does, it shouldn't take him long to build that right arm up.
