Low supply for breastmilk

How do i increase more supply for breastmilk? It's been 2 weeks and I haven't been getting enough milk or no milk at all! 😭 Since my 3rd week pp, one of the day I didn't eat much, milk totally decrease from that day onwards. I ate rice, soup and vegetable alot and hot water during confinment but my milk is still not increasing. I don't really latch my lo as she dosent know how to drink properly and quite impatient and with the current situation of my milk supply won't be able to latch her as she don't get any milk. I did express my milk but its sad that I don't really have much milk compare to a few weeks ago. It's been only a month since I give birth, and I don't want to stop producing milk Any advice? I tried lactation drink before, it does help but I only for awhile and I managed to pump till 30ml only and hasn't been increasing 😭 Expressing my breast, dosent even reach a spoonful and it gets depressing. #firstbaby #1stimemom #advicepls #pleasehelp #pregnancy
