No, I'm reading what he said, that she's a 2nd Dan who has problems with board breaking, she is good at everything else. The OP thinks being aggressive is the answer to breaking boards, says she's too timid with them. He didn't say she needs to spar more aggressively just that she needs to learn to break boards. Quite simple really.
Ok, you are right I am wrong. You obviously know more about this than I do.
Good Luck
