I have a similar problem with my Syrian, I sometimes present her more my fist than my flat out hand because sometimes she inhales my fingertips too deeply and goes in for a nibble lol. I think it’s sometimes just because it sticks out the don’t realise it’s all part of you, as Ria said with the scent idea I think that’s a good idea.

Also it is only day 4 so I’d be carefully handling her too much at this stage, try transporting her in a tub or something if she is coming out the cage and get her used to running near you and on you. Just sometimes I’ve had hamsters I thought were completely tame and picked them out the cage, and they have one scare, jump aimlessly and your back at square one. So thought I’d add this so you don’t accidentally startle them.
