Anak, please bring baby to the doctor or pediatrician right away, lalo na if newborn pa lang, cough in babies that young kailangan ng medical check kaagad para ma-rule out kung ano ang cause. A few of us moms have been through this, at ang general rule namin is hindi kami nag-wait pag may cough ang newborn kasi mahirap ma-assess kung serious or hindi without professional. Better safe than sorry talaga with newborns, 'di ba? Keep baby warm at humid if you can while waiting to see the doctor, but please go na.
