Do campbell dwarf hamsters stop biting?

[HalcyonW]

Hello!

I've had my 2 dwarf hamsters for a couple of weeks. I read that they need to get used to you before they stop biting/nipping, but as soon as I think they're accepting me, the next time they see my hand they bite it, even drawing blood (only a tiny bit). Might it be after I've washed my hands (e.g. maybe the hands smell soapy, so they don't recognise me?) Am I just being too impatient - after all, I've only had them 2 weeks.

Thank you!
