2 weeks old baby eating enough?

The doctors have told me my baby should be eating 8-12 times a day, but she only eats every 3-4 hours, which works out to 6-8 feedings a day. Normally we are closer to 6 feedings a day. She is still gaining weight (She is growing like a weed), and pooping and peeing the "normal" amounts. Should I be waking her up more to eat or should I let her keep to her own schedule?
