Aww sabar okay, 1.6kg at 32 weeks memang on the lighter side tapi still within range, a few of my mum friends pun pernah kena situation macam ni dekat tengah pregnancy. Makan lebih frequent je, focus on nutrient-dense foods like eggs, ikan, ayam, nuts, fruits kaya nutrisi, porsi kecil tapi selalu, and make sure you're hydrating well sebab sometimes dehydration boleh affect baby's weight gain. Kena follow up dengan doctor consistently to monitor, tapi don't stress too much sebab still ada time lagi sampai due date, baby boleh gain weight cepat dalam few weeks ni. Take care of yourself juga, rest enough, jangan overwork.
