This might be a silly question - but is her handwriting always bad? I mean, for my DS (granted he has super strong fine motor, so this doesn't exactly apply), while he CAN write beautifully... a lot of time (or if he is writing more than a few sentences), he will just get really sloppy. I think it's mostly laziness/rushing on his part. Again, this might be silly because you already ruled this out, but just in case she is rushing or something like that, I thought I would mention - maybe it's just a matter or taking her time. Or some combo of that and visual processing. Or just the latter. Or something else entirely. lol, super useful, I know! Best of luck, hope you figure it out.
