Aah mama, I feel you, susah kan when baby tak gain weight macam expected even after trying supplements. Honestly, kalau susu badan memang tak banyak, few of my mum friends actually consulted lactation consultant atau paediatric nurse, bukan just GP, sebab diorang tahu cara nak assess properly if it's a supply issue or baby's latch aje; sometimes simple positioning changes atau frequent feeding on demand helps more than pills. Since your baby dah 5+ bulan, best jugak tengok sama doctor or lactation person to check if baby okay and explore options together, bukan pressure ke, tapi dia boleh give guidance yang practical untuk situation you. In the meantime, jangan stress sangat because stress memang kurang susu lagi, so take care of yourself juga.
