When I was a kid my kitten Inky attacked my feet mercilessly in bed! Your question really took me back.
My 9 year old Dusty now attacks my kids' feet under the covers, but leaves mine alone. (Maybe this is a tuxedo cat thing - as both Inky and Dusty are/were black/white.)
Anyway, Inky definitely grew out of it. I had another kitten bite my nose while I was sleeping - that wasn't pleasant, either. I bought her a pacifier - didn't help. But time did.
I'm sure it will pass. (It's kinda hard to keep from moving your feet so the kitty doesn't attack, huh?
