Oo, normal yan, lalo na sa ganitong edad! Ang babies ay may kung ano-anong sounds habang natutulog, grunting, squeaking, parang sipol, kasi still adjusting pa lang ang kanilang respiratory system at digestive system. Pero kung parang labored breathing or kung worried ka talaga na may problema, better check with your pedia para peace of mind lang, lalo na kang first-time mama kaya totally understandable ang concern mo.
