Hiiii mama! Lungad (hiccups) sa 1-month-old ay super normal talaga, especially pagkatapos kumain, hindi yan alarming at magpapasa lang siya on its own, kaya don't worry! Pero since kapalit lang ng formula, best na i-check with your pedia kung may changes din sa poop or crying pattern, basta ma-monitor mo lang if baby is feeding well and gaining weight okay, and if the hiccups persist for like hours, sabihin mo na din sa doc on your next visit, okay? You're doing great, first-time mama!
