What is the enclosure? Pics? What do you use to measure temps and humiidty? What is the heat source?

Trying to feed 6-8 times in a 2-3 week period is a lot. Also you said you tried to feed 2-3 times in the first week or so.

If she has a lot of hides and 3 sides of the cage are covered so it's private and she doesn't feel exposed and the temps are correct, then leave her alone without changing the stuff, moving her around or bugging her about eating for a while so she can settle in. Babies are often nervous and need some time to settle in and from what you've said, you've been messing about with things a lot trying to make it perfect for her.

There's a ton of tricks for helping her be comfortable enough to eat. First is to make certain she has lots of hides, the proper heat/humidity and you might end up having to offer live to get her eating, then switch to F/T. Maybe you need to heat the FT a bit more? Can you use a hair dryer to heat the outside up mroe before you offer it?

Post up what kind of enclosure and heat and temp sensor you have, and I'm sure that folks will have plenty of suggestions you can do!
