Aww, itu memang common dengan newborns, especially when they're 1 month old sebab hidung mereka masih kecil je. A few of us mums tried saline nasal drops (like the ones dari pharmacy), it really helps clear that stuffy nose feeling, and you can use it a few times a day. Tapi honestly, if the grok-grok sound is getting worse or dia looks like struggling to breathe properly, better check with your pediatrician cepat-cepat to make sure everything okay je.
