Hand Taming and Biting

[Geraldinethesyrian]

I’m in the second stage of hand taking my new Syrian. She takes treats from my hand when held between my thumb and index finger, but as soon as I lay a few treats on my fingers and palm to encourage her not to fear my hand, she bites.
Am I doing anything wrong?
I wash my hands before each taming session, I tame her in the evenings when she’s fully awake and I leave her alone when she’s washing or eating. I left her to settle in for around 5 days until she seemed comfortable in her cage (I use a bin cage over the minimum size). She has plenty to chew on, and she does so regularly. I can’t find any information about what to to do calm the biting.

Hello, does she bite you very hard or is it more of a nibble? Is she drawing blood and causing you pain?
