Aww, jangan risau sangat lah mama! 1.6kg at 32 weeks is on the smaller side, tapi doctor tu dah tengok, dia je yang boleh monitor betul-betul dengan scan dan check-ups. A few of us mums went through similar, and regular scans + good nutrition made a big difference. Go balik jumpa doctor, tanya exactly what they want you to do, might be more frequent scans, better diet, or just observation je. Your doctor is your best guide here, okay? Stay calm and follow their advice, baby will be fine.
