Exclusive pumping tips needed

Rav

Hi ladies..

my bun is 2weeks old, I exclusively pump 8 times a day and twice during night. I only get 1oz per session and have to supplement with formula , my baby boy is born around 9lbs big baby and eats around 2-3oz every 2-3 hrs

Though supplementing with formula is not as bad, I want to increase my supply. He has a lousy latch and is used to bottle feeding. And falls asleep on my boobs whenever I try to nurse him, also because I have low supply

How can I improve my supply? I have tried everything oatmeal, electrolyte drinks, have plenty of water and I’m always feel let down and depressed due to this

My husband feels formula feeding is not end of world but I feel let down as a mom

Pls suggest what else can I do?
