I did read up a bit more on red leg, and I do worry that handling might stress her too much.
However... the jaw makes it virtually impossible for her to feed on her own in her tank, so I move her gently to the feeding box. She has figured out that the spoon I use to move the runners and other live food to her is a good thing, she lunges for it, expecting food. When she has eaten, with me helping with the spoon or changing the incline of the fiding box (she eats better on an incline), I pour water in the box for her to swim and wash. I gently pick her up to check her underside to make sure she isn't too raw around her mouth from hard insects.
She doesn't seem too stressed from this, she seems to understand that feeding time includes a bit of handling. When she is done, I put her back in her encluser and leave her alone. She poops in the water bowl so I change the water when it's soiled.

I'm thinking I might add a bit more ventilation. One of the things I read about red leg was that lower humidity was helpful.

She is growing steadily now that she actually gets food inside of her and I'm hoping that with time she will have a large enough mouth to eat on her own without my help. I'm trying to teach her that she can get food in her mouth on her own, but she gets overly excited when she is being fed so she just bumps her nose a lot. When she calms down she manages to get some of the food in her, but the spoon helps a lot. Worms and pinkies are easier for her to grab on to, but runners are useful for her feeding respons and variaton. (and my pinkie "farm" isn't produsing at the moment).

From what I understand, peat is nice for frogs, just as you mentioned, Dan.
