If it doesnt subside, see ur doctor again and for home remedy, dont expose her to cold, rub her chest with menthol after each bath, always cover her head with cap especially when u are outside d house, back her often to generate heat from within.
Dont self meditate. You doctor must have diagnosed your baby before recommending the cough syrup. If you think the cough and cold isnt improving,go see your doctor again. It's very dangerous to self medicate a baby
