Yours is a very little baby, so it is quite normal for her (or him -- sexing them at this age is extremely difficult) to be anxious and skittish, especially because she is brand new to your home. Give her time to settle down and relax. Here are some general pieces of advice you can try, but if she is still afraid of you after about a week, I will hunt down the guide to taming wild lizards that I wrote for someone else having a similar problem and paste you the link to it. I developed this technique working with literally wild species of lizard such as Western fence lizards and Northern alligator lizards, which are much less inherently friendly and tame than the bearded dragon is, so it should work very well for you. The others I have suggested it to have told me it was helpful for them. Honestly though such an intensive procedure probably will not be necessary. First just try the following small tricks.
-- The handfeeding trick is an excellent one. Continue doing that. In fact I would encourage handfeeding every meal. This will solidify in your dragon's mind the idea that you are not a threat, but rather a protector and a source of food and nurturing.
-- Wear a clean shirt for one day. Don't get it genuinely dirty, but allow it to pick up your normal bodily scents and odors. (Yes, everyone has them, it's normal, and even if you, or other humans, aren't conscious of them, animals are.) Then take off that shirt and place it in your dragon's tank. Ideally place it near or on the place where the dragon habitually sleeps. Having the shirt in the viv will help your dragon become accustomed to your smell. This in itself reduces a LOT of the fear factor. Once your scent stops being something new and scary and becomes a familiar part of the environment, one of the major things that triggers panic in her will be neutralized.
-- Never grab at her. Always try to pick her up by flattening your hand palm up (at first; later, once she's gotten used to you, palm down works fine too, it just doesn't give you the option of taking hold of her if you need to.) Then slide it under her body from the FRONT or SIDES, never from the back. Predators grab and clutch, but if you do not act like a predator, she will be less inclined to view you as one.
Hope this helps!
