Eh dari pengalaman aku dan a few of my mum friends, scan 5D memang lebih detailed dan clear, tapi baby boleh jadi berbeza when they come out, lighting, angle, swelling from birth semua affect how they look! Aku scan 5D dengan my second child and when he came out, his face shape slightly berbeda, but by a few days dah sama like in the scan. The 2D scans juga ok jer, they're more accurate untuk medical purposes, so jangan stress sangat about which one to choose, yang penting is baby's health check okay je!
