advice for our little black devil?

this is our newest kitty, Winona! she is wonderful, playful, affectionate, and she was a huge emotional boost for our other cat, Rozwell. however, i am literally losing hours of sleep because in the middle of the nigh, to early morning, she will hop on the bed and lay on my girlfriends face, incessantly trying to nibble on her ears, nose, neck etc. so i stay up to keep her preoccupied so gf can sleep. i always make sure she has enough food, so it’s not that. any tips on how to get her to stop doing this?
