bf milk supply

Baby is two weeks she was born with lip and tongue tie so got that fixed but latching is still a challenge.holy painful man!!!  I use a breast shield . Ok so my question I'm drinking mothers milk tea is there anything else to help with supply.? I make 2 ounces. And supplement as well. Someone told me to drink a dark 🍺 beer. But don't know ! And don't know what kind because I don't drink lol
