Help me! My 8 month old needs more Brest milk what do I do

Brandy

So I am a working mom and I express milk three times a day. I have realized I am not producing enough in one session.

Things I have tried with little luck

Oatmeal

Fenugreek

Fennel tea.

Beer

Heat

Power pumping

Also I need to add I live in china so things are limited.

Please let me know if you have tried something that works.

Help me keep my baby fed.
