Hi,

Drink 3L of fluids a day. Eat more carbo and proteins. You can try oats, papaya soup, seaweed, fenugreek. Also, keep latching on demand. From my experience, this is the strongest stimulus for breastmilk production. Also pump in between latching (like the halfway mark betwen 2 feeds) and try power pumping.

Drink more liquid. Can try green papaya fish soup, steam Threadfin fish or salmon. Drink milo or oats can help too. Alternatively is to pump after latch to send signal to your body to produce more milk.
