Momshie, honestly kami nag-start ng fluids agad, water, warm milk, kahit sabay-sabay lang, para ma-loosen ang phlegm niya! One of my mum friends swears by honey and lemon sa warm water, plus we make sure to rest ng maayos kasi yan talaga ang secret sauce para mabilis mawala, pero if it doesn't improve in a few days or parang lumalala, better check with the doctor na para sure lang!
