Ok Wanna -
I love OT, but it can get expensive. Here's my 'home version.'
1) lots of hand strengthening activities that are fun - kneading bread dough, paper mache, sewing, crochet.
2) how to hold a pencil -Dangle it between the thumb and first finger, then swing it around.
3) 10 minutes a day of 'handwriting without tears'

My Printing Book for example, or some of their 'readiness materials' if she isn't there yet.

We complained about our son's pencil grip to his OT in 2nd grade, and she said: Oh mine's much worse - and blew us off. Nice lady, but...

YMMV - but you may want to try a little hothousing first.

Love and More Love,
Grinity
