Sayang, I feel you, memang susah when supplies habis and wallet kosong. Kasi try reach out to local FB community groups or mosque/surau dekat rumah, sering ada moms yang share or donate pampers and formula, and some have charity programs especially untuk families yang kena hardship. A few of my mum friends juga pernah get help dari charity orgs macam Asnaf Empati atau local NGOs bila they really needed it, boleh jugak try apply. You're doing the right thing reaching out, jangan malu, semua parents pernah dalam situation susah at some point.
