She's cute.

I have a quite a few cresties at this point and they all sleep in odd positions. As for her calming down, that really depends on her. I have a few that seem to be naturally calmer than others. I don't handle my geckos much but some will sit still for a few minutes, others are little psychos and suicide jump a lot. I would try handling her, but if she's flightly naturally handling isn't going to make a difference. Hold her over something so if she doesn't jump she doesn't fall that far.
