Increase breast milk

I really need advice badly. Last night I just gave birth to my boy when he is only 24 weeks 6days. The most important thing is tat I gave birth in a very backdate county - Uzbekistan... an unfamiliar county when I went on holiday (gave birth because of some condition unexpectedly). Down here I can't get whatever I need, but can please advise me on wat food I can eat to boost breast milk for my baby? Today it dont seem to have milk coming out and I'm very worried. In hospital here they don't serve much. Hubby planning to get me out to a better place to prepare myself for our boy. And I'm already emotionally and mentally breakdown. Environment like in 90s and oso have communication problems. I really need help. #pleasehelp #advicepls #firstmom #firsttimemom
