This is not aggression. It's mostly attention seeking.
What you have to do is pick ONE method, do it all the time, and STICK TO IT. Consistency is the key. The puppy is only 10 weeks. That means that over a maximum 2 weeks of training, you've switched methods at least four times. What this means, is that if she persists, then she will get what she wants. You have to be more resilient than the dog. If you're going to ignore the dog, pull away quickly, and react whenever the mouthing occurs. You have to be consistent about what behavior is unwanted, and what the consequence is for that behavior.
