Sis, please check with your baby's doctor ASAP, lalo na if the breathing changes happen suddenly or your baby looks uncomfortable or palid. Two months pa lang si baby, so any changes in breathing pattern ay better safe than sorry talaga. A few of us mums learned the hard way na mas okay mag-worry and check, kesa mag-assume lang. Could be something simple like congestion or gas, pero kailangan talaga ng professional to know for sure. Let me know how it goes, okay? Sending prayers!
