I can't add to the great advice above, but I can relate from my own experiences. When she was little, my little girl Mallorn was (she still can be) very skittish and afraid of new things. To introduce her to new toys, I show it to her, play with it, and leave it outside of her cage where she can see it, slowly moving it closer during the day. Eventually, I rest it against the side of her cage, occasionally picking it up to reassure her it's safe, and when she nibbles on it or investigates, I know she'll be okay with me putting it in the cage. This has generally worked really well
Maybe your shy girl would approve?
Anyways, we'd love to meet her and she sounds like an absolute darling.
