Ay, ang daming laway talaga ng babies, kaya sometimes hard to tell talaga! Usually kung may ubo sya, you'll hear an actual cough sound, distinct sya, hindi lang parang throat clearing or spitting up, and mas madalas sya mangyari lalo na after feeding or pag nakatulog na sya. A few of us noticed din na if may cough, sometimes may slight fever or mucus sa nose, so observe mo rin kung may iba pang signs like sniffles o parang uncomfortable sya at night.
But if you're worried o nakita mo na persistent cough in a few days, better check with your pedia to be sure, lalo na ngayon may ganap na viruses. Moms get peace of mind lang knowing kung okay lang talaga ang baby!
