Awww jangan stress, 16 hari baru lagi sayang! A few of us went through the same thing, 20ml pump output yang bikin panik, tapi actually normal jer di early days, supply kita still establishing. Biasanya around 3-4 weeks baru terus increase, so keep pumping dan bf-ing (frequent stimulation tu kunci), minum banyak air, rest properly, dan jangan skip meals. One of my mum friends says consistency dengan direct bf sambil pump jugak helped her susu naik significantly after week 3-4, baby's latch jugak gradually better. But if you're worried atau baby tak gain weight properly, best check with your lactation consultant or doctor kay, sebab they can assess if ada any latch issues or other things yang boleh help. You're doing great laa, early days is the hardest part!
