Baby 4m demam, batuk

Runsing, sebab doc cuma bagi ubat demam..dah 4 hari demam..on-off. Cek darah ada slightly virus infect..doc cakap nothing serious. Cuma, batuk dia agak menggangu (for baby). Dia akan menangis setiap kali batuk..have done check home remedies but not avail..just sapu minyak aromatherapy for baby je skrg ni..kesian dia..kadang kita rasa mcm nak nangis tengok dia sakit..how to manage the situation since mmg takde ubat utk batuk for baby..
