2 of our kitties did this to our feet and legs as well, they were really young. Our hands also when trying to play with them. We thought it was normal kitten play so we didn't do much about it. We knew they weren't trying to hurt us, just playing. I would try the lemon for your feet, but like Luba said, not on the hands.
We cut their nails and that helped a lot. Kitten claws are very very sharp and can feel like a bite. You could always try a little spray of water when she's really goin at it! Good luck.
