Unless it is an infection, there is not much doctors can do about coughs. Over the counter cough expectorant is not safe for young kids. Chinese medicine is much more effective. Some other things you could try:
- Stodal (a naturopath you can find in drug stores)
- Rub eucalyptus essential oil (dilute with some olive oil) to rub on the chest.
- Rub some oil of oregano on the chest/spine of your kid.
