My daughter wants to play guitar...
I have 3 guitars she could use but they're all standard, right-hand configurations and she's left-handed.
My wife thinks I should teach her to play right-handed. Since she's never played before, it won't be like she'd have to unlearn anything.
However, I'm concerned that I could be potentially limiting her later on because she might not ever fully develop the dexterity she might have otherwise developed if I had just gotten her a left-handed guitar to start with.
