Sayang, baby weight 2.8kg at 35 weeks is actually normal and healthy lah, doctors can't predict exactly berapa berat when baby lahir, so tunggu je sampai delivery day! Since your first two babies lahir normal and healthy (3.75kg and 3.95kg), this one should be fine too, even with GDM. Tapi important you follow doctor's advice closely, if doktor recommend planned delivery, ada reason dia, especially considering weight + GDM. Trust your O&G and listen to what they advise for safest delivery untuk you and baby. You can do this!
