Its VERY normal for a puppy to bite and its something she will grow out of in time, I'd advise when you cuddle her and she starts biting make a loud OUCH everytime she does it and it will startle her, it won't work over night it can take a couple of weeks for it to work but it will, also if the OUCH sound dosen't work, put her into a room on her own everytime she does it and keep her there for 10 minutes and it will teach her that its wrong to bite. And never smack your puppy for biting as it will make them worse.

I did this with my Staffy and it worked wonders.
