office supply stores have rubber finger grips/cots, About 1-1/2" long and with a thimble she should be ok.

I give a third vote for nitrile gloves. I wear them for work and if you get the right size, they are like a second skin. Don't get too big, they need to be snug. You can find them in phermacies, farm catalogs, Harbor Freight. Stay away from latex or vinyl. They don't have the dexterity of nitriles.
