I don't handle hatchlings at all until after their first meal. I would suggest that you move her into a six quart tub, on paper towel with a hide on the warm end, and a water dish on the cool end. I'd use a small plastic flower pot saucer with an entrance soldered out like in the photos.

That's a 15 quart tub for a ball python that's a hatchling. All my hatchlings now are kept in six quart tubs.
