Baby 1 bulan jeluak

Aiyoh, reflux memang very common in newborns, especially at 1 month, their digestive system still maturing and the valve at the top of the stomach tak fully developed yet. Try keeping baby upright for 20-30 minutes after feeding and elevate the head of the cot a bit, but honestly lah if it's happening multiple times a day and baby seems uncomfortable or not gaining weight well, better check with your paediatrician to make sure it's just normal reflux and bukan something else. Hang in there, it usually improves by 3-4 months!
