Haha, memang ada je baby yang suka "buat rahsia"! At 36 weeks, kalau still tak nampak, kemungkinan baby positioned awkwardly or placenta blocking the view lah, bukan senang nak confirm kalau baby shy macam tu. Honestly, some parents tunggu sampai delivery day baru tahu, dan honestly² there's something special about that surprise jugak! Tapi kalau you really want to know, you boleh try 3D/4D scan at private clinic, sometimes they can see better dari standard ultrasound, tapi no guarantee lah sebab depend on baby's position juga.
