Aiya, burping sampai spit up sikit memang common dalam pregnancy, especially lagi bila dah 25 weeks, hormon dan baby pressure kat stomach semua jadi complicated. Tapi kalau dia severe and affecting your sleep, better check with your doc to make sure it's just reflux biasa and bukan something else. Few of my mum friends had this jugak, and some found it helped to eat smaller meals, avoid lying down right after eating, and keep pillows high when tidur, tapi ini macam trial and error lah depending on your body. Burp slowly, don't rush it, and if muntah comes out frequent-frequent or you're having pain, definitely see your gynae okay, don't wait.
