Eh possible je! Lagi-lagi kalau anak first datang awal, memang tendency anak kedua boleh datang awal jugak, tapi tak guaranteed lah, a few of my mum friends ada yang first 36 weeks, tapi second sampai 39-40 weeks, so setiap pregnancy is different. Since you're already thinking about it at 29 weeks, boleh discuss dengan doctor masa checkup nanti pasal history anak first you, maybe they can monitor more closely towards the end and prepare kau mentally for earlier delivery kan?
