When does she bite? If it's towards the end, she could be bored and having a chew, or frustrated with the slower flow. It helps if you know roughly when it happens because you can watch her like a hawk at that time, and you'll see a subtle change in position. It's not possible to be properly latched and bite because the tongue covers the teeth when actively feeding. If you see that shift, quickly unlatch and offer a teething toy. If she gets upset, and you were close to the end of the feed with one side, maybe offer the other instead. The faster flow might help.
If you do get bitten, I'd try to stay calm, but make it clear you are finishing the feed. I would put Alice down, and say 'Biting hurts mummy.' If she's happy to finish, she was probably just bored, if she cries, try relatching, and you'll probably find the feed carries on normally.
Also, if you ever find she bites and won't let go, don't pull her away. Pull in to your breast to cover her nose. It sounds terrible, but she will naturally open her mouth very quickly to breathe, then you can move her away.
Generally, it's a short lived phase, so try not to stress too much. Hope that helps!
