Nursing 12 times a day or even a little more is within the range of normal. I am pretty sure all my kids nursed at least that often at this age, and I had no problems with low milk production.
When you say baby sleeps through the night, how long is that usually?
Are you pumping at night because you are feeling full, or to have expressed milk for a stash, or because you are concerned about milk production or some other reason?
Has baby's gain been normal? Again that would be the most accurate measure to tell if something is wrong or not.
Breast compressions may help with this. But it might be baby is getting all she wants from the one letdown. Search Jack Newman Breast Compressions for a good article on how and why to try these.
