Increase supply

Jaclyn
I'm working on getting my son back to breast. He's currently 9 weeks and has been bottle fed since he was born due to issues latching and hasn't been to the breast since he was 4 weeks. 
I've recently tried to get him to latch which now he will but he doesn't stay latched because of my supply. 
He current eats around 30 ounces a day and I'm only producing on a good day like 17 oz. 
any tips on how to get my supply up? 
I've tried taking fenugreek, blessed thistle, goat rue, and a multi lacation supplement. Also tried increasing how much a pump. Nothing seemed to really help.
