Aww, ang mahabang ubo talaga ang nakakaasar, lalo na pag may holiday pa! While you're waiting to see the doctor, a few of us moms swear by giving warm fluids, like chamomile tea with honey or even lugaw broth, para ma-soothe ang throat, at making sure siya's staying hydrated throughout the day kasi tumutulong talaga yan. You can also try elevating the pillow pag natutulog para less irritating sa airways, at keep the room humid using a humidifier or kaya naman maligo ng mainit na tubig para sa init ng paligid. Pero since it's been more than a week na talaga, make it a priority to call or visit the clinic as soon as they open, prolonged cough can be something that needs proper checking, especially if may fever, difficulty breathing, or kung parang hindi pa rin umuubos even with home remedies. Hope your lo feels better soon!
