DD5 is not 2e (as far as i know!) but i have noticed that during last year's disastrous Pre-K experience, her grip went from a natural tripod to something very odd where she can barely see what she's doing - her hand covers the letters as she makes them and she is gripping the pencil like her life depends on it. she says she started holding it that way because the other kids last year held their pencils that way (typical DD!) and no one corrected her. that doesn't surprise me at all, since even with this weird grip her handwriting is strangely awesome - neat, regular and very small.
however, she's totally unable to do any kind of sustained writing - after half a sentence, she is cramping from the weird grip and all the stretching she has to do to work it out is really slowing her down. it's driving her crazy not to be able to get her thoughts out faster.
i just ordered some grips for her - i worry more about the ergonomic stuff than the actual output, but i'll post back if it seems like they're making a difference!
