Increasing my supply?

So I’ve been having a horrible breast infection for a while now. It’s been so painful that I had to give up breastfeeding for a while but now my breasts are slowly getting better after treating with creams and antibiotics but because of my baby not drinking I have lost my supply significantly, I still have milk but not nearly as much as I used to. Whenever my baby starts feeding my breasts are all soft because I don’t have enough in them.

Besides putting him to my breast and making him drink (which I try my best but I can’t put him on it too much because I’m not completely healed) what can I drink or eat in order to increase my supply?
