Ay, normal lang yan mama, lalo na kung FTM ka pa! A few of us had the same worry, ang biliw ay maliit pa lang at parang may sakit, pero usually it's just air trapped o di pa fully developed ang kanilang burping reflex at one week pa lang talaga. Try burping her more frequently during feeds (every ounce or two), and after feeding tilt her upright for a good 10-15 minutes kaya marelease ang hangin, yung iba namin nag-swear din sa side-lying position ng konti habang tulog. That said, kung persistent sya o may signs ng discomfort sya beyond typical newborn fussiness, better check with her pedia lang to be sure, pero most likely it'll settle as her system matures!
