Milk supply help son is 6 weeks old now

Christie

I’m hoping I can get some advice something anything! My son was 7 weeks early and I started pumping the night he was born, I was pumping every two hours I was starting to get 2 oz per breast but then I had oral surgery lots of pain no sleep unable to eat etc so my supply dropped to maybe 20ml every 2 hours ☹️ I tried nursing him then pumping to get my supply back but it hasn’t helped! I do the lactation cookies, the vitamins etc to try and help me pump more. I’m pumping because I’m getting ready to go back to work so I’m unable to nurse on demand like I would like too. Has anyone gone through this and was able to turn this around. Please help me I drink so much water and juice through out the day. 😪 I don’t want to give up
