Awww jangan sedih, 13 hari baru lah, banyak lagi yang baby kena adjust! Hiccups memang normal sangat pada newborn, tapi kalau dia susah sendawa dan jadi cranky, try ganti posisi, some of my mum friends swear by laying baby on their lap face-down (support the head well!) and rubbing in circular motions, or try burping during feeds every few minutes instead of waiting till the end. Also make sure dia latch betul if breastfeeding, sebab wrong latch boleh masuk lebih banyak angin. Tapi honestly, kalau dah cuba semua dan dia still sedu banyak hari-hari, check with your doctor or midwife just to be sure everything's okay, sometimes newborns just hiccup lebih, but better to confirm lah. You're doing great, mama!
