As said, if she runs up and 4D's, block it, almost nothing you can do to punish it. If she does 4D on wake up, you can 2B it for free.
In terms of approach, be risky but cautious because once she gets started, its pretty annoying to stop her. Use a combination of any of your pokes to try and a get a confirm(5C, 5D, 2A, J.C, Ice Sword) and lock that bitch down. Also tone down the full screen D Ice Car, and DP use; it works only 50% of the time on netplay :V
I seriously hate trying to get in on her, but its doable.
