My 2.5 year old daughter often has a lingering cough 2 weeks after a cold. can i give her cough medication if yes which one? we just give her honey

No cough medicine: It's not uncommon to have a lingering cough for a long time after a cold, as long as she feels well and eats and has normal activities. If she takes a turn for the worse, then she should see the doctor. Pediatricians don't recommend cough medicine in children less than 4 any longer. Lemon, honey tea is ok, vaporub on the chest is ok, using a humidifier in her bedroom when she sleeps may help.

See doc: You likely need to see her doctor again to figure out why the cough persists. Cough medication is to be avoided.
