Yes, letting her bite you now is "teaching" her that human limbs are toys, and you are setting her up for bad behavior later in life.
It's fun, and some people do play with their hands with cats, but it's best NOW to teach her hands are not toys - and introduce hands as toys later if that's very important to you. Best not to confuse the little thing during this phase.
Cats learn best through positive reinforcement and redirection. The lesson she needs to learn is that humans are not for biting, toys are.
Sharky warns about the risks of straws - and while you have to keep an eye on them, we have always used bendy straws. We would buy a big bag and scatter them EVERYWHERE. They seem to be a great consistency for teething kitties. When kitty attacks our hands or feet or whatever, since blowing the puff of air in her face isn't helping, just focus on the redirection. Grab a straw and encourage her to play with it. When she does, praise the heck out of her. If she goes for a hand, give her a straw and walk away.
Whenever she plays appropriately for the next few weeks, praise her a lot.
Whenever she goes for hands or feet, try to redirect her to something appropriate - praise her like crazy and encourage it - if she doesn't go for it, ignore her and walk away.
She needs to learn that she doesn't get attention for bad behavior - she gets attention and praise for good behavior.
The straws do get chewed up after a while, so when you see a lot of holes in them throw them away, because kitty can ingest little pieces of them - but that isn't a risk until they're over-chewed, so just don't let them get to that point.
This phase should only be a few weeks to a month or so.
