Which instrument should a child start on?

Well if music isn’t for girls, do I have to un-train my daughter from playing guitar and piano and singing? If so, I just lost the lead vocalist in my acoustic band.

Piano, Absolutely
Its what any small hand can tinkerr with, and usually its what we all learn some simple stuff with. Now adays, you can buy a simple Casio keyboard for a xmas present for cheap, and let the kids play on that!
