Aih, I understand la, NT scan yang berulang tu memang stress! Honestly, a few of us tried walking around the clinic, doing squats, or even changing positions every few minutes before going in, tapi mostly it's luck of the draw dengan baby's mood yang hari tu. The sweet stuff memang boleh help stimulate baby, tapi sometimes they just want to sleep or face the wrong way! I'd suggest checking with your sonographer atau OB, they might have tips specific to your scan setup, and if ada any concerns about the NT measurement itself, better to get their professional opinion direct. Sabar je, mama, some babies are stubborn like that!
